What Should I Feed My Catfish? | My Aquarium Club
Here comes the tricky bit, so far I have stated that the preferred diet of those catfish described as predators would be other fish in the wild. When housed in an aquarium however, this is not necessarily true, as most predatory fish will adapt to a diet that does not include live fish (I must point out that I am not suggesting or encouraging people to feed live fish to their predatory catfish, even though it is natural for them to feed in this way!). I have personally kept "Predatory" species of catfish and have fed them successfully on a mixed and varied diet that has included pieces of trout and frozen foods.
I find that when feeding the truly nocturnal species of catfish, they relish good quality granular foods, sinking catfish pellets and tablet foods. I also like to feed them on frozen bloodworm that I add to their aquarium just after lights out time. Some fish keepers swear by feeding live foods. When feeding live food you need to ensure that is disease free. If you wish to feed live foods such as Daphnia, I would recommend that you culture your own in an old bucket to which has been added some rabbit droppings or some fresh sheep droppings. Once established you should have a good supply of clean live food, that can be fed without the worry of introducing any diseases to your catfish.
They are omnivorous and should go after all fish food that you place in the aquarium. Some feel that the irridescent shark should be given more carnivorous type rations as juveniles and to mix more greens into their diet as the get bigger. Aim for a varied diet of flake foods, frozen foods, algae wafers and catfish pellets.In the wild they are omnivores, and consume invertebrates, plant matter and algae. This diet can be recreated in the home aquarium through feeding them a diet that includes a high quality sinking pellet, and frozen foods, including frozen bloodworms, daphnia, blackworms and brine shrimp. If you are looking for a good sinking pellet, one of the best is , which I use for many of the catfish that I keep.These bottom feeders are going to eat all of the uneaten food that the other fish leave behind. It’s important to research your tank’s variables before just adding one of these catfish. Another amazing benefit to keeping them in aquariums is they eat all the uneaten fish food that sinks to the bottom. If that fish food were to just sit on the tank bottom.. it would create nitrates and in turn hurt your water parameters. Whatever it wants. It will eat most any foods put into the tank. Feed them every couple of days or so catfish sticks, meaty pieces of fish. They are well known for swallowing smaller aquarium decorations.
