Corals per gallon?

[Sir Alex]

I know this is kind of a dumb question, but how many corals should I get to fill up a 75 gallon tank real good?

well, that depend's on the coral's, for example, about 500,000 mushroom's or,17 galaxy coral's or, 4,000,000 xenia or, 1 starburst and in 5 year's, you'll have nothing but starburst.. so there's no real answer to that. coral's will fight for space they can, and do kill each other..I think if I were you I would buy a bunch of frag's space them apart and watch the magic, keep in mind sps's require alot of light! I would say around 4.5 to 5 watt's pg..

So corals will just keep growing and growing?

 

[Waddi]

Yep then you frag em and make money!! :p
I have frag my Star polyp twice since i got it! Haha it grows like a weed.

It depends on the type of coral, and how big it is.
