Ok so yeah I was in a hurry to get fish into my tank and I picked up some cheap damsels a while back..... the thing is, I would now like to take 'em back to the pet shop... they're small little suckers at about 1 1/2" to 2".... I've only got two and I REALLY don't want to rip apart my aquascaping to get 'em out......... any advice on catching these suckers?????
