I'm in the planning stages of a 30b or 40b frag system and I'm trying to put together a fish list. The only reason for fish will be for coral food, algae control and possible pest control. The tank will be bare bottom so I don't know how a wrasse will like that, but i would like a yellow corris wrasse or similar for pest control. I also will be looking for algae control aswell, a tang would be great but I think my only option for that would be a small baby yellow tang that would have to be moved to a bigger tank once it starts to mature. A blenny could also be another good choice, is one better then the other? I used to have a starry that was nice, but I've read that a lawnmover would be better. I also would like several other small fish for added coral food, I like blue/green chromis but don't like dealing with them killing each other off. What else could be a good alternative to chromis, maybe orange liked cardinals or similar? The tank will be pretty high flow as it will be mostly sps, and there will not be any rock in the display portion. There will also be a few zoas/palys, LPS and a large clam for filtration, so I can't deal with any fish that will mess with coral. Any input would be awesome.
