Help with my Angels!

[livewyr25]

Hi, recently i noticed that both of my angels had white spots on their bodies, so i raised the temp of the water to 83-84 degrees and started treating with Aquarium salt. Today i noticed it looked like one of the angels tails has almost disintegrated. he is still able to swim fine in looks like, and the other angel, is top fin is mostly missing also. there are smaller tetras in the tank with them and i have never noticed any aggression between them. please help!!!! thanks!

What other type of fish do you keep
with the angels? sounds like somthing is
doing a bit of fin nipping.

Your angel could have fin rot.
