Yeah, i have both and they seem to be doing great. All my rock, sand came from a 6 month old tank. half the water is old and half new(not that, that maters because there isnt much bacteria in water columns) All equiptment was used in the 6 month old tank so it was basically a swap of tanks. I waited 1 month and then added the fish, anemone, zoos, and mushroom.
Tell me if I am wrong but i think i should be alright levels are good in tank.
