OK, so I have a 125 gallon tank, only 7 fish in it, and over the last 10 days my water has been getting really cloudy, I mean 24 hours after a 25-30% WC it is noticeably cloudy. It never has done this before, established tank. My 5-6" peacock eel, which had previously been very visible and sociable has been missing for 2+ weeks, and now the tank smells distinctly of dead fish. Logical conclusion is that he died somewhere buried in the sand, of which I have approximately 2" Carib sea Tahitian moon black sand. I have taken apart filters, cleared filter lines, taken out every decoration(3x!) and sifted though the sand in the tank 3 seperate times and for the life of me I cannot find this dead eel. Does anyone have any tips(other than siphon out 120 lbs of sand) or tricks to find this bugger? Really not enjoying doing water changes every other day to keep the tank clear and I can't imagine having a rotting eel is good for the fish either.
