I am trying to stick with a Central/South American tank still...just not sure about certain species yet. I have been stumbling around all the lfs trying to get an idea. Although, I found one that had very small peacocks, labs and other africans for $2 each. That is tempting me to do an african tank...
All in all, I want either a single species breeding tank or a predator tank with a bichir or two, oscar(s), some kind of cats...
For now, my two female bluefin killies are loving the tank!
