What's with my Potter Angel

[Cu455]

What's with my potter angel? It has cloudy eyes and messed up fins. He is also just hanging out behind a rock instead of actively grazing. Ammonia and nitrites were 0. Nitrates were between 15-20, but I did a 15 gallon water change after testing. He started look bad yesterday. He was a good eater. He ate pellets. I haven't caught any fish messing with him.

I was going to treat the tank with kanaplex but only have enough for 20 gallons. I also have melicate green but can't find it. My tank is 90 gallons with a 40 gallon refugium.

they are a very delicate fish they take a long time to acclimate. How long have you had him?

 

[Cu455]

4 weeks total. He has been in the display tank for about 10 days. He was looking great then he looks like this. It is possible he got stung by my dwarf zebra lion?

One eye is real cloudy the other eye isn't that bad. Only one pectoral fin is damaged. I just turned on my night light. He came out and his swimming wasn't that great. Now it is much better. I soaked some pellets in kanaplex and used the rest of what I has in the tank. He is also eating.

Doesn't look good, and to make matters worse, even when they seem good, settled in, eating everything...they just die! IMO if it doesn't make it, don't try another one!...Sorry, hope it recovers.
