ok here goes i have a 55 gal available i want to make an order with jeff rapps he has pairs of true red terrors at about 5 or 6 inches a piece. my question is how long if i could keep a pair of true red terrors in a 55 gallon or should i just get a Hemichromis frempongi from jeff at about 6 or seven inches. i am upgrading to a 125 soon and a 90 gal soon
