This morning my beloved flame angel died. Im still pondering why he died. Tested the water and found no ammonia, nitrite, or nitrate. Temp. was at 76. Salinity at 1.026. Had no heath problems. Eating fine. Maybe he died of old age? Had him for 2 years and I dont know how old he was when I bought him. Also about 2 weeks ago all my 3 snails croaked. So my tank has only a Tomatoe Clownfish and a Blue Damsel. Im looking for another fish and a cleaning crew. All have to reef safe. Can anyone point in the right direction.
