Well for some reason my plate coral did just fine in my biocube under pc lighting but once I moved it under halide lighting it doesn't seem to like it at all. It is truly beautifull when completely opened up! I got rid of my biocube so I can't put it back in there. If anyone wants it let me know! I am asking $50 beings it is a XL plate coral. I may take partial trades. Maybe a koralia #4 powerhead( or just a big powerhead) let me know.
