Jaypime - Not trying to be a downer here, but your Huma is going to outgrow that 30g VERY quickly. I am sure that he is 1" now, but triggers are notorius for being fast growers.
IMHO - save your money on decorating your 30g and get a 90g. If you want it to look better, get a couple of clownfish, 6 line wrasse, some Fire shrimp and take the trigger and eel back to the LFS.
