Yep thats me I have two perc's and a Clarkii or should say had. The Clarkii would have killed the two percs so I had to sell him back to the LFS. I did however have anemones which made him a very agressive fish!! He would go out of his way to attack both of them, I tried them in my 25 gallon and then upgraded to a 72 gallon and neither tank worked. I wish you all the luck with your fish and I guess sometimes you never know.
