This is a picture of my boy, Remus, when he is perfectly healthy except for a tail injury, which healed completely up recently. Other than the split, that is his natural, healthy appearance.
I'll get a picture of what he looks like right now if I can and post it later. The camera has bad quality.
He looks normal, except for 2 things. He has two small missing chunks in his tail. I can't tell if it is tail rot or if he bit it. We've had him for months with no problem. I noticed it yesterday, and it was not there the day before. I don't think it has gotten worse today, but it is hard to tell because the damage is still exclusive to that spot.
He has something else that I have never seen before. Upon inspecting him today, I saw that, when he swam fast enough for his ventrals to go all the way against his body, that there was something ORANGE hanging down in between them it looks like.. What the heck?? What's going on?
