Why do I need to use supplemental diet?

Two reasons:Nutrition - Good commercial staple fish diets are the most complete foods available, and the easiest to use, but they are not perfect. They may not offer the nutrients found in live or fr ozen foods. A balanced diet should include staple processed food, as well as freeze - dried, live, and/or fr ozen foods. For herbivores, it should include a vegetable - based food; for carnivores, a meat - based food.Variety - An aquarium is seldom comprised of a single species, but even if it is, these fish would not be satisfied with eating the same food day - in and day - out for a lifetime. In the wild, fish eat a variety of foods to get all of the nutrients they require. In your aquarium, your goal should be to replicate this experience. Providing a range of staple, fresh, and supplemental foods improves fish nutrition, and the quality of their lives.

How often do I need to feed supplemental diets?

We believe that feeding supplemental foods 1 - 3 times per week can be very beneficial.

What could happen if I feed the wrong type of food to my fish?

Some fish only eat plants (herbivores) and others only eat animals (carnivores), but the majority of aquarium fish eat both plants and animals (omnivores). Plant - eating fish that are fed animal - based foods will not be able to digest the foodproperly, which may cause internal problems such as constipation. The same is true of strictly carnivorous fish that are fed only plant - based materials. In fact, they may become ill because they cannot obtain the proper nutrients. Thus, it is critical that you match the food to the feeding habits of the fish in your aquarium. Nutrition problems usually result from feeding the wrong type of food (plant - based or animal - based; sinking or floating) and feeding improper amounts, be it too much or too little. Some of the more commonly observed problems with poorly fed fish include lateral line and fin erosion, hole - in - the - head, weight loss, diminished color, stunted growth, listlessness, and disease outbreaks.

If I have many types of fish in my aquarium, how do I get them to be selective about the foods they eat?

Tactics. Most aquariums contain a variety of fish including fish that feed on the surface, others that feed mid - water, and still others that only feed on the bottom. Hatchet fish, for example, have upturned mouths that are suited for taking food off of thesurface. Tetras are mid - level feeders and have forward - facing mouths best suited for grabbing food suspended throughout the water column. Catfish have sharply down - turned mouths, ideal for bottom feeding. It is essential that you provide foods that are appropriate for each feeding level and that they are nutritionally complete. Because most fish will poach on the foods of others, you may need to use a distraction or timing strategy. For example, distract your bottom feeders by feeding them sinking pellets first, then waiting a moment or 2 before adding floating foods for your surface feeders.

How much food do I need to feed?

As a basic rule, fish should be fed once or twice a day with a quantity that they can fully consume in 3 - 5 minutes. To start, feed each fish an amount equal to the size of their eye. Overfeeding is much more common and detrimental than underfeeding.The quantity of food you feed your fish is very important for their overall health and the health of your aquarium. Overfeeding can result in uneaten food that will decompose, causing an increase in nitrogen products such as ammonia, or harmful bacteria or fungus.

When are vitamin and mineral supplements needed?

One of the key benefits of vitamins and minerals is that they are stress fighters. Whenever you suspect your fish might be stressed, it is a good idea to use them. For example, if you are about to add new fish, do an aquarium renovation, ormove, the use of supplements will help your fish better weather the stress.

    Perfect for algae eater

    By Metalalgaeeater on Oct 20, 2019

    nice product! Great price! My 10 inch pleco gobbles these up! My crayfish enjoys them too, he takes them and brings them to his little cave to eat later, shrimp like them too if they can beat the fiddler crabs!

    They love them

    By Alicia on Aug 6, 2019

    I have a CP who is about 13" long & knows exactly when feeding time is. He tries to beat my 15" red tail catfish to these. They both love them! I have an albino bristle nose who also enjoys them too. I usually put a fork in a whole cucumber for them to enjoy- but this way I don't have to fetch a fork at the bottom of the tank when they are finished!

    Great for the price!

    By Demeter on Aug 8, 2019 top1000Contributor

    Honestly I mainly use these for my live white worm and grindal worm cultures, which in turn feed my loaches, bettas and cichlids. For the cheap price it seemed like a great deal for my shrimp and plecos too! I could live without the added color though, I've noticed a tint of green in my worms since I started feeding it to them.

    Dissolve quicker than wanted

    By Christina on Jul 7, 2019

    I have 4 good sized plecos but I have only seen one actually eat this food. I am pretty sure my other fish eat it after it dissolves in the water so I wish it didn't dissolve as fast as it does maybe have it last a day instead of an hour.

    We have tried many wafers and alot of them change the water color or make the water smell bad. This brand does NOT. Our breeding Plecos love it. We highly recommend this brand.

    I am not sure

    By selah on Aug 29, 2019

    Either its dissolving in the water or the plecos are actually eating them. Not sure.

    Snails Love It!

    By Michelle on Sep 27, 2018

    Bought this for my mystery snails and they love them. Put one in and they ate it right up in a day. Even my frogs pick at it. Bought this one because it's one of the only brands that doesn't put copper in it, which is poisonous to snails. Great product!!
