Hey friends, one of the things I often am asked is what things are safe to feed to your reptile. Specifically in this case I'm going to talk about fish. Some fish species contain thiaminase, which can cause thiamine deficiency. You don't want that happening to your reptile, so I suggest avoiding those species. The main fish that we would feed here, include salmonids (salmon, trout, char) and tilapia (any cichlid is ok). If you fish or have someone who does fish, anything in the sunfish family (bluegill, pumpkinseed, crappie) is okay.
I'm going to post a link here that has a list of both fish that contain it, which you should avoid, and a list of fish that do not contain it, so you can figure out what to feed your fish. Avoid goldfish, and anything else from the carp family including minnows and koi. No catfish. No herring family. The list is very long, but few people will have Brian access to this many species.
