Niger acting reclusive and swimming a bit strange

[skmcobra]

I posted a few days ago that I believe I have internal parasites in my fish as they look clear on the outside. I was able to get PraziPro in from Amazon Sunday and treated the tank. Unfortunately it was too late for my Emperor Angel which died that day. I believe the internal parasites came with that fish 2 1/2 weeks earlier and spread to my two triggers. I've also treated my tank in the past two weeks with Copper Power just to be sure no external parasites were returning as I had Velvet wipe out my tank over 3-4 months ago. That all being said the Clown Trigger is acting normal...swimming around, eating both frozen food and algae strips. The Niger comes out and eats a little bit then goes back into hiding. He looks completely normal. However he is swimming slower and seems to have some difficulty swimming downward. Triggers are really fast, darting around at feeding time, but he is about half speed. Plus he usually eats non stop till I quit feeding them but he'll eat about 5-6 pieces then stop and go back into the rocks. Any ideas? Should I get any other medications?

What type of copper are you using? What level is your copper concentration? It could be the combination of the medications causing sensitivity and loss of appetite.

Per my OP above I am using Copper Power which claims to be 60x less toxic than other copper treatments. That is why I gave in to copper since I didn't have any inverts. I tested it last night and it was around 1.75 from what I can tell on the crappy API test kit. I got some API General Cure today at lunch and went home to soak their food in it. I'll feed them it when I get home and see what that does. The Niger was our swimming a bit when I walked in but went back into hiding. I fed them just a bit and he didn't seem too interested which is VERY concerning since up till today he has been eating at least a little bit.
