Okay I have a 46 gallon bowfront. It is set up with 40 pds of ls, 30 pds of lr(i am getting 30 more pounds this weekend), a fluval 305, and a 400 gph powerhead. Temperature is steady at 78 degrees, and sg is it 1.025. I have a few questions. First, I am purchasing some lighting off of the internet. I know I want coral in the future, so can someone give me some suggestions on some lighting for this. Is it hard to find lighting for a bowfront? Second, when I add my clean up crew, how many hermit crabs/snails can i add to this tank? All help is appreciated!
