Well i been checking out info in building a small frag tank JUST for Z's and P's, and i think im going to go with a 15gallon tank.
Just need to figure out what light and other goodies i will need
Hopefully soon i will have lots of frags avalible
I highly recommend LEDs for zoas and paly's.
That would be the only thing I would use.
I would do a 2:1 ratio of 3W Cree XP-E Royal blue: Cree XP-G Cool white.
If you have alot of reds I would also do 2-3 Cyans. 1 on each end and one in the middle.
W/O lenses it would spread and cover nicely. No spotlighting if you have it 6" above the water.
i agree with that nanonewb, i am personally a fan of MH and was originally thinking of led's however when i think of led's i think of party lighting, not aquarium lighting.
