I guess Ill go with the two perculas and probably a goby or blenny or something. One last question: how the heck do I get metal halide retrofits to go onto my tank?
<<"Retrofits" are intended for attachment to/modification of an existing hood/fixture. I expect you'll have to "DIY" a hood/fixture for your 30 gallon tank to utilize the retrofit and keep the MH lamps at a suitable distance above the water>> I’ll skip the anemone and cardinals. By the way, I do have plenty of experience with FW. <> Thanks again! <
