Ok guys, here's an update and some help needed. It took me 3 days to catch her but a pretty nifty DIY trap out of a plastic bottle, zip lock bag and fishing line did the trick.
I put her in a 10 gallon tank with heater, 20-30 gallon filter (no carbon), and some live rock. I took 4 days to get the tank up to 0.5 copper but literally after the first day all the white Ich spots disappeared.
I've been testing nitrates and ammonia every day. Today I noticed ammonia registered at 0.25. So I did a 50% water change and ensured copper was at the same level. I added a circulation pump because I felt I wasn't getting enough circulation. I originally tried a wave maker which was way too powerful for the tank size. The smaller pump seems to be working more appropriately.
Since I did this she is out swimming around more and eating better. My question though is that she's still not behaving as she did before the switch. Could this be ammonia and/or flow? Lack of eating? I'm convinced I'm on the right track to get rid of the Ich but I don't want to cause her other harm. Any advice based on what I've shared??? Thanks so much as always!
