I seem to have an outbreak of snails in my tank which seem to be feeding on some white mold or fungus I had to do a big cleaning all my fish are dead how can I get rid of this mold or fungus problem and are the snails a problem or not please help.
I use sea fans in my 150 gal tank and never have had a problem. The snails might have been the cause. Suggest you clean ypur tank with hot salty water to kill and snail eggs, snails or funguses. In the future to control snails I would suggest you look into clown loaches (min 3 ) or golden dojo loaches. They love snails and snail eggs. Use them in all my tanks.
