why do so many people seem to think its a good idea to recommend clown loaches for ALL snail problems, no matter the size of the tank and no matter the conditions clown loaches require? sorry for sounding annoyed, but this has really been going around lately...i think this is the fourth such recommendation (all by different people) i've seen in the last week on AC.
:duh:
in any event, i've found that you can really reduce the population by simply picking out as many as you can, and also removing the little egg clutches wherever you see them. once you get the population down, it's easier to get on a schedule of lesser feeding and more rigid maintenance, both of which will keep the snail population limited.
