These are a couple pics of my recent fish, Koran angle, dogface puffer, picasso trigger, I also have a fimbreated moray eel, I am still trying to get a picture worth posting.
Sorry to be a downer but you will probably havta get rid of a few of them eventually as they all get over a foot and the fimbriate will get up to 4' which im guessing is the length of your tank.
