Then about 3 weeks ago i added another blackmoor to the tank. At first they got along fine, but now the little loach won't stop bullying the pair of blackmoors! He chases them around the tank and sucks onto their bodies. He tries chasing the goldfishes too but they're a lot faster and more of a challenge so he generally leaves them alone apart from a bit of tail chasing. He never bothers the pleco or the other loaches. At first I thought they were just having a bit of harmless fun, but cleaning the tank today I had a nasty shock when i noticed the blackmoors have got painful looking white patches on their sides where the loach has damaged their scales!
I immediately caught the bullying loach and put him in a plastic clear container of fishtank water and left it floating in the top of the tank. He's nice and calm, but as soon as one of the blackmoors swims up to the container he gets nasty and thrashes around trying to get at him!

What should i do to help the wounds on the poor blackmoors heal? and is there anything i can do to calm the loach down so he'll get along better with the blackmoors?
