Hello all. I feel sad to bring this up here, but I'm afraid to say that one of my RES is not doing too well. I've been super busy for the past few weeks and haven't spent much time with them aside from a quick feeding before I leave the house for work. Today when I fed them, I noticed one of my RES has these large abrasions on the back of his neck as well near/on his limbs. Now, I'll admit to being a bit neglectful, but these are serious wounds that appear to have shown up overnight.:Here's a link to an album
with some photos of the wounds. The images are too hi-res (and a bit scary) to embed effectively
My thought is that these are biting abrasions caused by my other turtle. I have two of them (4" RES, 3" painted) in a 50 gal tank, both males. I know that's not optimal (70+ gal is what I should have), but Its a lot better than the 4 turtles I used to have in there, before I found homes for the other two. There have been times where I've noticed my painted turtle latching onto my RES with his teeth, not letting go until I come over and get involved. But from what I can tell, that was a rare and odd behavior, and these wounds have appeared very quickly, despite that occasional behavior happening for awhile. It is curious that these wounds only appear in places that the painted turtle could feasibly latch onto.
If these are not scars from bites, then my only other thought is that this is some sort of infection.
Anybody seen this before?
I feel like a horrible turtle parent, but I just don't know what to do.
