Well, the rams are on hold. I simply couldn't resist a pair of kribensis today. They were two of the most beautifully colored kribs I've seen (the male is actually what I think is referred to as a scarlet). At only 2", they were already "flirting" and showing some outstanding spawning colors.
So now my question is: Do you think they can stay in the cube (30 gallons, 20"L x 18"W x 21"H)? I can move them to a bigger tank if you think they need more space/length. But if I aquascape correctly, do you think they can be permanent residents of the cube?
