 little monsters !!!

I had a horrible time with these little monsters, being relatively new to fishkeeping i relied on the knowledge of my local petshop who assured me they would be fine in my community tank, needlesly to say it was like a child in a sweetie shop and munched it's way through a few of my fish and injured my large clown loach who subsequently died. So beware before considering these little blighters !!!
