This afternoon I found my 2 year old sailfin plec lying dead at the bottom of my tank. I can't understand what happened to him. Was swimming around last night and then when I came home from work I found him. Water sats all ok bar pH which had dropped from 6.5 to 6. Feeding community with flakes, fresh bloodworm, dried bloodworm, peas, algae tablets.
What have I done wrong? Any ideas what might have happened.
