I'm starting a 38 gallon reef tank and would like feedback. I have 40 lbs of sand 50 lbs of dry rock a 50 gallon filter 4 39 watt bulbs I plan to put 2 clowns a neon goby and a flame angel. I would like either the flame angel or leopard puffer. But I know Id have trouble with a clean up crew with the puffer. What do you guys think. Any advice I would like to hear as I am still newer to saltwater.
