Going to be setting up a 50g frag tank Tank will be the lowboy 48x24x10. It will be mostly be SPS. I would like a small tang in there maybe a small Yellow eyed Kole or even a small convict tang just to constantly be grazing. And then maybe one other fish like a wrasse to keep any pests at bay. I would also like to add a few snails so hopefully something that wont eat my inverts. Thee tank will be connected to my main display which is 187g. Any thoughts for fish?
