i was planning fw rays for the 150 but apparently all my tanks hold right at 7.8, so instead of doing the peacocks in the 40, im going to do them in the 150. i have a brand new fluval FX5 that i plan on filling all the center chambers with biomax. i also plan on using a 404 for mainly chemical filtration, and 2 303s that will be mainly biomax. do they enjoy a strong current to play in the way the mbunas do? if so i can add a strong powerhead just for the flow. i plan on using 150 pounds of estes' black marine sand on top of egg crate. i will have a black background. i have some rock work, but plan on adding more, probably mainly black slate. i have a 6' double bright on there. how many should be able to have in this setup and are there any changes that i should do? i plan on weekly 50-75% water changes as with all my tanks.
