I got a few maricultured colonies a few weeks ago. A neon green stag, looks like green slimer but might be close relative, and what someone identified as maybe a purple plana. They are even more colorful than when first bought and have fantastic PE, moreso than when they were in the store. The green one already looks like it's growing. The third looks like a Acropora secale and it looks purplish under a actinics with optical nerve burning green polyps but under whiter lights it looks beige colored. It does seem to be developing a bit of purple/pink coloration at the tips so it might be early yet to change things. I have it up pretty high with pretty strong flow. The green polyps do extend more at night than before but they are smallish polyps to begin with. I was wondering what placement people keep theirs in. It isn't white white looking as if it were being bleached but can you bleach a coral and have the polyps happy like that?
