hey have a planted tank, 120x50x45 and currently has guppies, 1 siamese algae eater, 1 glass catfish, 3 khalui loachs and 5 bristlenose's and a few old neons which are slowly dying of old age one by one, but i dont know what else to add, would prefer to get something, non-livebearer and not cichlids, that would readily breed in the tank. any ideas would be great. (pH is around 6.6-6.8)
