Angel Fish Problems

[Jakeychs]

Please Help

So i have a palm size angel fish and a group of red eye tetra's. and i have noticed that my tetras are what looks like biting the angel fish's fins. but i looked at the angel's fin and it looks fine. i read that these tetras are peaceful and good community fish. but i am worried bout my angel getting stressed out. so im looking for some advice on what to do. they are in a 100g tank, good water quality and good lighting.
Thank you

How many tetras? Sometimes adding more will solve nipping problems. They would rather play with each other, than bother other fish. Otherwise either the angel or they have to go.
