ok i was in my tank cleaning the glass and one of the tubes for my skimmer when the clam i bought(it was called like a nitrate reducer or something)grabbed a hold of my cleaner thing.it wont let go or open.what should i do?
if its not a photosynthetic clam, try aiming a power head right at it . . . the excess current might make it move. If you just pull it off though its likely to die.
