heye since ive had my Bala sharks few months back when they were 2-3inch they allways have been losing tiny peices of there scales, just wanted to know if this is natural.. sometimes they get a bit of a scare n run into the wall so on, could this be why ?.. also ive heard its a sign of ich. All my water contions are fine and i do 20 percent water change every week. so if any one has the answer to this mystery =] id love to know. ohh yeah there about 10cmsish now =] in a 8 foot tank, and i got 6 of them =] i love them dearly
