a bit of help needed on stocking please. my tank is 42 inches long, the height is 18 inches and the depth is 15 inches. its been housing guppies and swordtails for months but i'm really quite fond of cichlids. really like labeotropheus trewavassae (sorry it don't say its common name in the book i've seen a photo of it in) and was kinda wondering if them and the lemon cichlid would live happily together? i also like rams and the blue zebra cichlid. thanks.
