The only fish I see in there are 3 nice sized discus (Beautiful by the way...1 pigeon blood and 2 turqoiuse?) and a nice group of black neons. Not too small of a tank for that group, as it seems she keeps up on water changes. If you want to add anymore fish...then yes, it's time to upgrade. Nice setup though.
125g semi planted. 2 silver angels, 14 silver tips, 16 white fin ornatus tetras, pair of Nicaraguense, pair of nototus severums, trio of firemouth cichlids. 2 FX5s, 1 1500gph circ pump, 2 48" LED lighs, and a HUGE piece of driftwood.
Thanks, everyone! I change my water 75% every other day using my water change system, so everyone is very happy. In fact my discus laid eggs again today. The boys fight sometimes, but the little girl breaks it up usually so things are relatively peaceful in a 3 discus tank.
