5 year old tang is not doing well in qt. for Ich. Recently stressed it out when adding new angel fish to the main tank and repairing the wave box. THis fish liked to hide behind the wave box but when we took it out for repairs it went nuts from fear and ran into the side and top of tank. Stress (or the new fish) brought on the Ich so they are in QT.
QT water parameters test good
heat 78 degrees (too warm?)
Fluval bio filter running.
Plenty of plastic fittings to hide in
wrapped the tank sides to darken it.
Medicating with low dose of copper.
FIsh seemed okay until today (2 weeks in qt.). Yesterday was swimming in the bubbles - today acting limp. I'm wondering if the Fluval is not putting enough oxygen in the tank. Or maybe enough copper - could the Ich be affecting its breathing? Been trying to get copper test strips before additional dosing, but LFS
only open weekends.
I welcome any suggestions to keep her alive. SHe actually looks much, much better than 2 weeks ago - good color and very few white spots.
