It took me a long time to get my mean little damsel out of my 12 gallon, we'd just put in our anemones, and clowns, and he wouldn't leave them alone, kept picking on the blenny too...the funny thing is, the clownfish were actually defending the blenny, hovering over him and such, we finally did catch the little booger, and our store gave us credit for him...i got my clowns, anemones and a few other things from SWF.com ...here...and i love them to death!!! The koran willl lose some color as he grows...that makes me upset since i'd love to have a koran who stayed marbled...
