Hi everyone, thanks in advance for your help!
Recently I gave Remi a new toy. It was actually a dog toy that I hung up in his tank with some fishing line. He absolutely loves this toy and for the first few weeks he had no issues with it at all. Last night he managed to get tangled up in the fishing line and got squeezed by his own weight. Luckily I found him and got him free.

He seems totally fine, he has a little damage to his scales and one very small spot where I see what I think is muscle (First picture is a closeup). THe injury is very small, about the size of a single scale.

I've taken the toy down and after he heals up I'm going to try to find a new way to hang it safely.

The injury seems very small to me but I just wanted to check with people who know a little better. Does this look like something I need to take him to a vet for? Or clean in any way? I've been keeping his tank as clean as possible but is there anything else I should do?

Also if anyone has ideas for how to more safely hang this toy, that'd be awesome too.

Thanks!
