i too can attest the attachment to my fish. I had a Lemon Peel angel named Taster, guess what killed him? I miss him and the the two Hammer head corals he took with him. I two have a Bio cube 29 gallon. It is covered in aptashia, I bought those nimbus from Brandy to get it under control. I am wondering how you modified your hood to fit another light? please post info? thanks Kevin
