Yea, that's always the hard part. It's especially true for fishes, and it's especially hard. They don't grow, but the impact that each fish has on your tank can be so dramatic, it's very different than just one more colored stick, or one more puffy rock thing.
I've got 2 female McCosker wrasses on order from the LFS, and if/when those come in, I think I'll also pick up a helfrichi firefish, and be done. DONE DONE DONE. NO MORE FISHES.
The only reason I'm okay with that amount of fishes, is the filtration is pretty good, and I should be doing water changes more frequently than I have to now (every two weeks, but I don't really feel the need if I'm at 0/0 for nitrate/phosphates). I also want to get a tiny bit of nitrates into the tank, so maybe this will help while adding to the beauty.
Also, I LOVE HELFRICHI FIREFISHES. Now that I have a J-O-B I can afford to get one
