No, just have no spots for them on the rocks.. lol.. actually, top of tank seems to bleach more SPS corals than grow them. Putting my SPS corals on the bottom they seem to not bleach and regain colors more. The tank, stand, sump were free, clowns were free, live rock was free, sand was free, and just about every coral in the tank was free, and 90% of them came out of Guillo1's tank and where just frags laying on the ground in his tank, or in his sump 1/2 dying. It was either let them die completely in his sump or just take them and toss them in my tank and see what happens. So far none have died although they have been through a lot. All I have into this tank $ wise is 2 pumps, 1 for return, 1 for the ATS, the ATS parts ($10), screen top, heater, 2 powerheads, light holder and LEDs, so less than $300 total for everything you see in the pictures.
