With the current fish I have does anyone have opinion on how many more I would be able to add? I have heard its 1 inch of fish per 5 gallons of water but from what I'm seeing in a lot of tanks it seems to be more than that. Does it also depend on what type of fish you keep, or what area they occupy? I have read the sticky about stocking but I'm just not to sure what to do here and I don't want to overstock the tank. I was thinking I would be ok to add two 3 inch fish (when fully grown) or one 6 inch fish (fully grown). If you have any recommendations it would great to hear them. Right now these are some of the fish i was looking at. I don't plan on adding all of these.
1 more firefish
a flasher, fairy, or leopard wrasse
Diamond Watchman Goby or another type
These are just few we have been looking into, I'm trying to find a peaceful fish/ coral safe that will get along well with the others.
