What is an Amphipod? On AquariumDepot, you can buy 1000 of them for 19.99. They make great little fish or coral food. For controlled environments, amphipods can add variety to fish tanks and aquariums. They can help with the clean up process in the tank by cleaning up the excess debris, plant, or algae or they can make great food for the fish population.
Fish tank and aquarium owners may welcome these bottom feeders with open arms and they can be of great benefit to any tank. With careful planning and management, these crustaceans can be a benefit to the environment. The big problem with these little fish is that if they are not enough fish to feed on them they can overpopulate. Directions need to be followed. Add about 1/2 the bag per 25 gallons and make there is enough fish in the tank.
At AquariumDepot, they sell a mixture of amphipods and copepods. These both function the same way, and there is no way to differentiate between the two of them. Amphipods are larger than copepods, because they can be seen at a distance. This mixture can be a great addition to any tank if directions are followed.
