Hi, I've had rams spawn and raise fry in 5, 10, and 20 gallon tanks. A compatable pair is important, as well as a lot of hiding places such as bog wood, caves etc. I always include a flat rock as a spawning surface. They like fine gravel, but it isn't required. I agree that moving them from a large tank to small would make them crazy for awhile. dave ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@majordomo.pobox.com.
