HAHAHAHA! As i have told my wife i will only stop if i have no room to put fishes in. I would love to have a community tank though,lets say 12 aro's in one tank? That is another story maybe in the near future hehehehe.
I think those are a community of X-backs bro,that is why the backround is white and both sides of the aquarium for the fish to develope and cross nicer.
