You can try feeding them commercial fish food or meal works from your local pet store. If you would like a consult, you can provide pictures and we can give you a better idea of what kinds of fish they are and if they have special requirements for their diet. Hope this helps!

It sounds like you need to take a trip to your local pet store. The clerks there can help you pick out an appropriately size tank with proper filtration and heating that can help keep Sushi healthy. They can also let you know what water treatments you'll need for the water in your area, as well as test any water you bring it to see if it is OK for Sushi to live in. Pet stores will also carry commercial goldfish food which is a balanced diet that is given to them. It should have feeding instructions on it so you know how much is appropriate to give to Sushi.

Thanks for reaching out about you fish. It is believed to be a Comet goldfish. Water quality and nutrition is the key to success. Testing water parameter for pH, ammonia, nitrite and nitrate will give you guidance for a healthy environment. Purchased food should be rotated out every 3 months as vitamin C and other nutrients degrade over time. Trying to maintain water temperature can be challenging with out a heater, but most fresh water fish tolerate some changes. Good luck.

Koi fry can be fed daphnia, brine shrimp (live or freeze dried), krill or hard boiled eggs ( remove the yolk, blend, mix with water and pour into the tank). Feed them multiple times a day. Once they grow some, you can switch to "fry powder". This is basically finely ground koi pellets.

Glass catfish should be kept in groups of 5 or more or they will not feed properly. They will eat flakes better when there is competition from other glass catfish. Glass catfish do prefer other foods and need more than flakes. Try to get brine shrimp, blood worms, or California blackworms from your pet store. It is also important to keep them in a dusky environment, they do not like bright lights, and will be more active in the evening and night, and therefore also eat during that time. Water temperature should be around 75–81 °F, better at the high end.
