In my refugium i have purple and some red looking stuff .
growing fast.bad or good the Oyster just looks cool wanted to

Looks to me like normal sponge growth(a good thing)...The oyster looks more like a flame scallop, did he just appear or did you purchase him somewhere? Both are filter feeders and will help with water clarity
