stupid question

[digital-audiophile]

I think sometimes you just need to take a chance. I bought a decent sized brown acro just the other week becuase you could see a hint up purple at the tips. Now in my system the purple is spreading down the branches, it will be a really nice coral when it colours up

ya i'm with jkhchris, they do try to often go cost effective as possible alot of times, when i got my cup coral colony a couple months ago, it was a dull brown under there lights and i really just got it for it's sheer size, but when i got him settled up high in my tank he turned an intense fluorescent green, wierd color change, by far the most intensely colored hard coral in my tank. Then again they were running 10k's, so the true color wasn't exactly shown. good question though i always wondered that too..

Like Greg says...if you look really closely you can get an indication of what colour a coral might go.
