I had a few juvie large Angels (emporer, blue griddle, and blue face), a few tangs(yellow, powder blue, and blue hippo), small Angels (flame and bicolor) and a few other species( bicolor goatfish, diamond goby, raccoon butterfly, various anthias, and porcupine puffer).
I have a 14 gallon biocube "reef" but don't think I'm going to try corals because I have a few more fish that are probably not going to be too reef safe.
