well i noticed one in my tank couple months ago... took it out and put it in a bowl of water for pictures later. later... go back to check, it's gone O_O it must have crawled out and wandered around.
well yesterday while adding bioballs to my diy canister filter, i found 2 more. i smashed one and kept the other one in a plastic container WITH A LID. well now i know its a leech i want to kill any others because i think they're the reason for my yellow shrimps declining numbers.
after googling a bunch of stuff it seems only the following choices are available: clout, fluke tabs, salt dips, and total annihilation. none of them except the last one worked very efficiently. can i dose prazi pro? i really want to get rid of these buggers... they better not touch my crs >:O
