I am new to this forum, I am a part of caudata.org for my axolotl but they don't seem to handle turtle questions. I have a juvenile Res, and he has recently started to eat less and even when I give him pieces of earth worm it is like he doesn't swallow them as easy. My daughter noticed right around the time this started that he looked as if he pooped out blood. What it was was he had eaten a piece of his shell that he had shed. It was one from the outer ridge, so not a big one. The piece did look stained red. I assumed that this could be the problem but he doesn't seem to be getting better. His water is warm enough and he is active like normal. When given his regular turtle food he eats some, but not as much. Goes crazy as usual for worms, but just seems to have a hard time getting it down. I am not sure if tank size could have an issue? The man that had him before had him in a 20g tank and wanted to get rid of him. Now he is in a 40g breeder. Now that he has grown I am going to get him a nice big tank

just has to wait a couple months until tax return. Any help would be great! He seems fine otherwise.
