injured fish

I have an angel that somehow got stuck on the filter intake. It has
what looks like small cuts near the tail fin. These cuts appear to be
from the fish swimming backwards on the intake trying to get its self
free (scales peeled backwards?) I would like to know if there are any
meds that should be used to help this heal and/or prevent any
secondary infections from the open wound.

Melafix should help provided an infection has not already taken hold. It
is a worthy preventative. Unless you see signs of other problems
developing it is a good mild medication to start with. Stronger
medications should be avoided unless you see signs of a spreading infection
(e.g. white stringy slime or continued necrosis of the wound).

The addition of a small amount of aquarium salt will help to relieve the
changes in osmotic pressure caused by the open wound. For angelfish
perhaps try something as mild as 1 round tbsp for every 5 - 10 gallons.
Salt in itself is also a mild preventative against things like secondary
fungal infections.

Angelfish are normally strong enough to avoid getting inhaled by filter
intakes. Was your angel showing signs of weakness to begin with, or is
this just an extremely ornate veil angel?
