So i wanted to get a few opinions on this. My friend has this red tailed shark that is currently living in a 5 gallon tank and he never takes care of it. He said i could have it if i wanted to but I’m just not sure. What if it brings disease into my current tank? Will it even be compatible with my current stock? I just feel so bad for the poor guy. I know my tank size isn’t ideal either but it’s definitely better than his current situation. I have a 37 gallon tank with 2 platys, 3 mollys, 6 Julii Corys, 10 neon tetras, one rubber lip Pleco and one dwarf gourami. Here are some pictures of the fish. What are your thoughts?
