Sorry your angel is unwell.

The ventral fins (long feeler type ones) look quite short and possibly the tail fin a bit damaged too?

What other fish are in the aquarium?

I've noticed the tip of his dorsal also looks a bit nipped. His ventral fins might look shorter because one is part black - gets me sometimes.

We have two other angels, two platies, a guppy, a gourami, a pea puffer. Our zodiac loach gets ornery around feeding time, but I don't think he or our other bottom dwellers could even do anything.

This angel is the biggest fish in our tank. The puffer did bite him once, but we've not seen anything else from them, we've seen them get close to each other many times and they just ignore it.
