I just picked up a new bullfrog tadpole from my job(PetSmart). I currently have him with my 3 goldfish in a 30 gallon tank. I will probably move the goldfish to a 10 gallon and set the 30 up as his permanent home. I've been feeding him fish flakes, and I also have aquatic reptile pellets that I have been trying to give him as well. my question is, should I feed him something different, and how can I tell he's even eating? other than that, any advice on the little guys care would be great. picture will come, I just need to take them off my phone. also, his name is Polio.
