jovreefer, your pix could have been taken in my tank...a 54 with 1 250 mh Reeflux 12000 and 2 actinics, 12 hrs actinic, 8 mh, good flow, lots of lps, kalk drip. My crocea is maxed out, as I understand it, about 5 inches, about 5 rows of scutes added since I got him. He insisted on being on the sand no matter how many times I tried to put him in the rock. This went on all the year I had my first incarnation of this tank. WHen I moved and increased flow considerably, with a fuge and kalk drip, I noted him trying to attach to bits of things. And nestled him in a pedestal made of a dead piece of monti cap. 2 years and going strong on whatever goes in the tank: I don't feed him special.
