FAQs

How long does pellet food last after it's opened?

All our pelleted products, when kept in a cool place, free of direct sunlight, moisture, and high humdity or heat are good until the best before date on the package. You can find this in the lower left hand corner of the back side or bottom of the package. For optimum results it is best to use the package within 90 days of opening it.

What is the difference between pelleted and flake fish food?

Hikari® diets are developed specifically to meet the nutritional needs of the fish they are meant to feed. Pelleted food by design is more compact, providing more nutrition in the same amount of space, therefore care should be taken when comparing pricing on flake food versus pelleted food. In most cases, your best value is a pelleted food. Additionally, pelleted foods are more visible. This allows the user to monitor the amount of food their fish are actually eating and to remove any food not consumed by the fish within a specific period of time. This helps eliminate over-feeding as well as the water quality and disease conditions associated with this common problem. It also tends to save food which translated to a lower feeding cost than flakes. The advantage of pelleted over flake food can be summed up as better nutrition, better value, and less water quality problems and maintenance, something all fish keepers are happy to experience.

What is the difference between a sinking diet and flake fish food?

If you use flake-type foods or floating pellets, the top/middle feeders usually eat most of the food. Our uniquely shaped diets that sink rapidly make the nutrition readily available for your bottom-feeding aquatic pets. Additionally, our pellets have been formulated to maintain their shape longer than competitive products because we know bottom-feeding fish prefer to graze.

Why are pelleted foods priced so high for small packages?

Pelleted food is more compacted, providing more nutrition in a smaller space than flakes. For example, the human equivalent would be a bag of potato chips versus a bundle of carrots. Both items take up the same space but the carrots are more dense and nutritious than the potato chips. A small amount of pelleted food may have the same amount of nutrition as a much larger amount of flake food. Also, pelleted foods float or sink slowly, allowing the user to monitor the amount fed, helping to eliminate overfeeding, water quality problems, and diseases. The food will also last longer, providing better overall value than flake foods.

When should I feed my fish frozen foods?

Hikari® Bio-Pure® Frozen foods can be fed as a supplement to most any regular diet to provide additional nutrition for your fish. Our Blood Worms are excellent for improving spawning for discus and angelfishes specifically, and are a great source of protein and nutrition for all other freshwater and some marine fish too. Hikari® Bio-Pure® Daphnia is an excellent food for aquariums that have been recently medicated or are experiencing a bacterial problem of some sort. It clears the digestive tract of fish within five to seven days and helps improve digestion because it is a natural laxative for fish. Hikari BIO-PURE Brine Shrimp is an excellent food for all tropical and marine fish, high in natural algae and packed with nutrition. If more algae is required for your fish check out the Hikari® Bio-Pure® Spirulina Brine Shrimp. We also offer Omega infused Brine Shrimp for marine fish. Most marine fishes require diets rich in various algae, sponge, crustacean and other nutrition packed ingredients. Hikari® Bio-Pure® Mega-Marine, Hikari® Bio-Pure® Mega-Marine Algae and Hikari® Bio-Pure® Mega-Marine Angel provide these ingredients allowing your tangs, angels and other marine fishes to flourish. Other Hikari Bio-Pure frozen foods are specific foods to supplement dry food feeding and add variety to your feeding regiment. Ask your local aquatic specialty retailer which food is best for your specific situation.

Does floating or pelleted food cause goldfish to float upside-down?

Care should be taken when using a floating food for goldfish. Floating food contains many air pockets which allow the food to float. At times these pockets don’t fill with water when put in an aquarium, causing actual air bubbles to form within the food. This can cause problems with some goldfish. To avoid the majority of these problems, we suggest you feed the appropriate pellet size for your fish (or one size smaller). Soaking the food for a few minutes prior to feeding can also help eliminate this problem should you continue to experience it. Many times this problem is caused by an improperly formed swim bladder valve which doesn't allow the air to escape properly. It is not directly caused by the floating food. You can also try our Sinking Goldfish Excel® as a great option to help eliminate this issue or our Goldfish Wheat-Germ to help your goldfish recover.

How much food should I feed my koi?

Feed one (1) pellet of food per inch of fish two (2) times daily when the water temperature in your pond consistently stays above 68°F. Feed half of this amount when the water temperature is consistently below 68°F but above 60°F. Adjust feeding accordingly as the temperatures drop below 60°F as the metabolism of your fish will continue winding down and too much food can cause health issues. When temperatures are colder, above 82°F or variable, we strongly suggest using Hikari® Wheat-Germ and moving down one pellet size from your normal choice.

Which Hikari diet will improve the chances of breeding my koi?

A combination of Hikari® Wheat-Germ and Hikari® Spirulina will prepare your koi for reproduction. It’s important to note that when spawning occurs the oxygen level in your pond can be rapidly depleted by all the new fry taking their share. Also, adults will eat the fry as a natural response, as will predators who you may not know have been spending time around your pond. If you want to avoid all the fry being eaten, remove them from your pond until they reach 1″-3″ depending on the size of your koi and your filter system.

Which Hikari® diet will help the coloration of my koi?

Hikari® Gold® is a daily, color enhancing koi diet that aids in the development of brilliant red and orange coloration. Hikari® Excel®, rich in spirulina and wheat germ, provides enhanced coloration while readying your koi for reproduction. Hikari® Spirulina provides excellent coloration of the red and orange areas of your koi while creating a noticeable richness in the white areas as well. Our Saki-Hikari® Color Enhancing Diet is what breeders choose to bring out the championship color of their fish and is part of our professional lineup for koi.

Which Hikari® diet will help my koi build body mass?

What is Gammarus?

Hikari® Bio-Pure® Gammarus is another form of shrimp that contains significant amounts of natural color enhancing ingredients fish can readily utilize. It’s actually a better color enhancing food than Krill and naturally provides a great mix of amino acids fish can utilize too. Best of all it’s highly flavorful which makes it easy to feed to most aquatic pets, especially larger carnivorous fish.

What is the difference between Cichlid Gold® and Cichlid Staple?

Cichlid Gold® is a daily diet that also offers color enhancing benefits, whereas Cichlid Staple is primarily a maintenance diet providing above average growth (with added color enhancing benefit. It will help your fish develop their natural coloration but cannot enhance it).

Is freeze-dried krill good for arowana?

Yes, when used as a treat, Bio-Pure® FD Krill is a good supplement to a normal daily diet like Food Sticks or Jumbo CarniSticks®. Also, Bio-Pure® Frozen Krill or Gammarus are also excellent choices.

What do I feed a discus with a body the size of a nickel?

Each Massivore Delite® pellet is approximately 3/8″ in diameter and 3/16″ thick and is equivalent to 1.8 average sized goldfish without all the hassle, bacteria or parasites they carry as hitchhikers.

Do I need to feed my algae eater (plecostomus) or will he get enough food from the algae growing in my aquarium?

Algae eaters (plecostomus) require ample amounts of vitamins and minerals in their diet in addition to algae and vegetable matter. Many of these vitamins and minerals are not present in algae grown in an aquarium. Hikari® Tropical Algae Wafers or Mini Algae Wafers provide a highly balanced diet for all plecostomus and other algae eating inhabitants of your aquarium. Best of all, they maintain their shape for an extended time allowing grazing fish to eat at their leisure.

My corydoras eat the Algae Wafers I feed to my plecostomus, why should I feed them Sinking Wafers®?

Catfish (corydoras), loaches and many other bottom feeders have small downward-facing mouths which keeps them from efficiently eating a product like Algae Wafers®. The unique shape of Hikari® Tropical Sinking Wafers® has been designed to allow these types of fishes to easily grab and ingest the small elliptical pellet. It provides them with ready access to a food with more protein derived from higher protein sources and has been developed specifically for their dietary needs.

What type of cichlid is Cichlid Excel® made for?

Hikari Cichlid Excel® and Sinking Cichlid Excel® were developed for the special dietary requirements of African Cichlids. They require a diet rich in vegetable matter. They contain spirulina and wheat germ, both of which are highly digestible. Expect brilliant, natural coloration when using these diets.

How much Betta Bio-Gold should I feed my betta?

For smaller bettas (1″-1.5″ in length from the tip of their nose to the base of their tail, before the fins) we suggest using Micro Pellets® and feeding 6 pellets twice a day. For bettas 1.5” to 1.75” feed three (3) pellets of Betta Bio-Gold® two (2) times a day depending on your bettas eating habits. When your betta reaches full size (about 4″ in length) feed no more than four (4) pellets three (3) times a day depending on your betta’s eating habits.

Ultimate® says to avoid using with potassium permanganate, why?

The potassium permanganate will interfere with the effectiveness of Ultimate®. If you are using potassium permanganate we suggest waiting 24 hours after use using carbon or some other media to remove the potassium permanganate.

Can PraziPro® be used as a food additive instead of adding it to the whole tank?

Keep in mind that praziquantel is a bitter ingredient and may make it difficult for some fish to readily accept when mixed in a food. Soaking food in a mixture of PraziPro® and water as directed on the bottle and letting the pellets absorb the water is an option. See this link for more information.

Is carbon or an ammonia removing filter material safe to use during treatment with PraziPro®?

We would suggest removing it. Additionally, you want to be sure all the other medications you have already used are out of the system before any treatment is started. We suggest a minimum of 24 hours with carbon in the system to remove any residual medications if you feel you may have some present.

Are there incompatible water conditioners that should not be used with PraziPro®?

The major issue is we do not know, and most labels do not state, what they have in them or how they remove chloramine, chlorine or ammonia. There are a number of products that are sulfur or sulfinite-based that can cause issues with efficiency and dissolved oxygen levels. For this reason we recommend using Ultimate® or ClorAm-X® and Stress-X because we know they are 100% compatible.

Is there a dosing schedule I can follow that would allow me to reintroduce carbon filtration in the hope of reducing the nitrates further while continuing to medicate my tank?

Not while treating the tank. To totally eliminate a fluke issue using PraziPro® you would have to treat the tank a minimum of 4 times for 7 days each in succession. You could run carbon for a day in between treatments as long as the water change is done before the next treatment is initiated. We suggest using ClorAm-X® or Ultimate® for the water conditioning during the treatment to avoid any incompatibility problems.

When should I expect to see results from PraziPro®?

Within 3 days, depending on the severity, you should see noticeable improvement.

Would I be better served to increase the PraziPro® dose to speed a cure?

Never increase the dose beyond what your actual volume of water is, this is never recommended.

Can I treat with more than one type of medication simultaneously, and if so what kind do you recommend?

Never use more than one medication at a time under any circumstances as you could eliminate the benefit of one or the other or both and cause issues with incompatibility, dissolved oxygen levels, more stress to already stressed fish or other issues. Also, never use any medication prior to using PraziPro® that has copper, including copper itself. Copper can render PraziPro® ineffective.

Do you ever have coupons for your food?

We offer special promotions from time to time for our Facebook and Twitter followers and through our preferred consumer email newsletter, which you can register for on our site here.

Inside the package there is a small pouch labeled "DO NOT EAT", what is it for?

The packets contain oxygen absorbers that help eliminate oxygen inside the package prior to your opening it and help maintain the freshness required for optimum quality. They are not edible and should be left inside the package, to be discarded when the jar or bag is empty.

What does the statement on the Bio-Pure® FD containers mean? ("For maximum success, the contents should be used within 90 days of purchase")

Any freeze dried (FD) item is hydroscopic and therefore tends to absorb water from the air. This process can cause the product to oxidize and in extreme conditions can cause it to be unusable for feeding. For this reason we include an oxygen absorber in each package and suggest using all the product within 90 days of opening to maximize freshness. Following these guidelines will provide the best overall product experience for you and your aquatic pet.
