My flame angel is mostly active during the day. Today he has been "hiding" in the live rock cave i made and not coming out. He seems to be sick. I All levels seem to be fine. temp-80 ph - 8.2 0 no2 & no3...any suggestions?
How long have you had the Flame angel? How old is your setup? Is the flame getting bullied by either the Clownfish or Damsel? With a small tank there could be some territorial issues going on.
Just my opinion here but a 20 gallon is kind of small for any Dwarf Angel.
i have had the tank set up for going on 3 months, he gets along with the clown fish. no real issues, sometimes the flame with pick on the damsel but mostly harmless. he just has been acting weird. not active at all.
