I already have five in there, but I was reading up on them this morning and found that they are best in schoals of 6 or more..I am one shy of that schoal mark...should I add one more? Am I at max capacity for a 25 gallon tall with my five tiger barbs? They seem pretty active and have plenty of room, the tank has live plants and is pretty stable stats wise and has a wide open carpet area in the front and left side with thick tall plants to the right and center to right rear...just want to know my limit for tiger barbs..thanks..and I look forward to utilizing this site more as I am a new member this moring :thumbsup:
