RBT Taking Over Part Of My Sump

Thought folks might enjoy a pic of our large RBT that lives in my sump with 6 other RBTs on the same rock

We seem to just be lucky. We bought one about a year and a half ago that has turned into 16 of them, no kidding, through multiple splitting. As far as the sump goes, we had to put about 6 of them in the refugium part, to rescue them when they were in the display rank getting picked on by a long nose butterfly (yea dumb move to have put him in the tank to begin with). Now they are splitting too...crazy how somethings grow like crazy in our tanks while others take so much more effort to achive moderate growth.
