9 rummynose tetras
6 cory cats
1 red tail shark
1 clown loach

Symptoms:

One of my seven Angels has not eaten for quite a few days now. No other signs of illness. Should i be worried?? All my other fish eat their hearts out but this one doesnt seem interested. Ive also noticed his top fin has 'curved' over. Like a killer whale does in captivity. (hope that made sense.) Happened quite a while ao though so maybe un-related... Any ideas why? Is he depressed?? I notice a little amount of bullying but nothing serious and its a big tank..so.....im stumped.

First, how are your other water parameters?

You might consider isolating this Angel with a tank divider or breeder net. Or if there is a bully, this fish can be temporarily moved to the breeder net.

Consider adding something new to the diet such as live, FD or frozen foods you have not previously tried, such as Blood Worms.
Frozen Omega or Spirulina enhanced frozen brine shrimp is excellent.

Make sure you have calcium cations present and I have also found that products containing Indian Almond Leaves help stimulate many Amazon River Fish (or similar softer water ) as Angels
