Recently set up this 55g...added a pair of Blue Acara and a pair of Firemouths about two weeks ago. All is going well, but there is very little "action" in the tank..of course both species are small right now, but they hide quite a bit and always hide when I approach the tank. I'm considering removing the Firemouths and adding a school of some sort of Barb, to use partially as a dither fish and just to create some movement in the tank. The largest Firemouth started picking on my BN pleco, so the pleco was removed to my 10g, but the Acaras are a little smaller than the Firemouths and he's turned his attentions on them now (not horribly but chasing them here and there). Would the barbs be a good idea? I was thinking either Green Tiger Barbs (5 or 6 of them) or some Odessa barbs (not sure if they are too small for this purpose). What do you think?
