Does this look like tailbiting to you?

I've never known of Wartooth to bite his tail but then again he has also been sick lately. Looks like he's been chomping at it. You decide.









Also, does Waffle appear to be biting his own or does it appear to be finrot/splitting?

No... I don't think it's Finrot then again I've got my own issues and can't think straight *Trying to keep his own Betta from murdering the new fish*

Drax did this once to his own tail with almost BARBER like precision in a straight cut. I think VT's trim their own tails now and again when they get too long.

In the one picture it does look like tailbiting (blue with lots of red). It looks like he's chewing between the (not sure what the proper term is for fish) veins of his tail. Feathery ends are another good indicator of fin biting. I'm not sure about the other one tho, sorry.
For fin rot and fin biting the best treatment is lots of clean water. Daily water changes are advised. In the case of tailbiting this helps prevent fin rot from occurring. A high protein diet can help with fin growth, live foods if possible, or frozen (not freeze dried) foods.
Sorry to see he's tail biting, mine has done that a few times, it's so frustrating when you try to do everything right for him and they do that.

Yeah. This is the first time I've suspected him do this but he didn't start showing signs of it until I put him in a 0.5 emergency tank when he was recovering from being sick. He probably got bored. He's been in his big boy tank for about a week or two now.

I think the first one looks like finrot, but I'm no expert on it. The edges look dark and not frayed..more like melted away and his tail looks shorter than it should be...

The 2nd, is it possible that he ripped the fins on any decor? I always suspect tailbiting as the last possible cause... check water parameters and keep an eye on him :)

Okay. I'm not sure. It could be finrot but I'm going to keep an eye on it.
