I see the picture of your tank, but you seem not using undergravel filtration, are you try the deep sand bed way to help doing the filtration? With the setup like this, I would strongly advise undergravel, though you need to prepare for maintanence problem, clogging of the system sooner or later, it is an effective filtration method I ever seen.
Light is not your main concern if you go for FOT, I suppose you won' t keep reef, right?
The fishes you listed are all good for starter, I would like to have goby or cleaner shrimp as the first tankmate, this would add to the least problem of introducing new fish later, the key is to add less aggressive fish first. Be careful not to add to big or too fast to the tank.
