I just gota 14 gallon biocube myself after having the biocube 29 for almost a year or so. I am planning on replacing the lights with AI sol nano lights or the AI regular haven't decided i love me some sps corals so i will need to get the right light. That being said i have some ricordia mushrooms a bubble coral star polyps two types of gonistrea a green stripe mushroom and a pink stylophora and they are going great with the stock lights, the Pink stylophora have great color but is very touchy and will be moving into the 14 gallon as soon as possible. any mushroom would work. Star polyps bubble coral, xenia can as well. Also if you are going to get some sort of dwarf angel get it last. I don't recommend them for small tanks but people get them and they need to be added last. I hope that helps you with your lighting. I am still learning as well but this is what works for me and i have never had any problems. I also bought a RODI unit to help with water quality.
