So my wife talked me into finishing my reef. I've all ready traded in my big banded cat shark, and added file fish to take care of those apts.but still have 2 sharks to trade in. Plans are to expand my reef to each end of the tank and to add one more light, think four of these lights are just much. I have two maroon color clowns that I've had for ever,thinking going to up grade them to the 240 once sharks are gone!
