what are you talking about? have the sprouted in different regions? but im not sure what you are talking about so i will try to name them all
-tan=zoos
green bubble=bubble algae
red thingie=not sure but it is some type o LPS it looks like. possibly even a blasto? not sure on that one, but if they are randomly sprouting up, then it is not any lps.
my guess is you were talking about the bubble algae? so here is what i know about it. comes in tanks often high in nutrients or older bulbs. many fish and inverts eat them, but they reproduce by spore, so everytime something eats it, it jsut releases the spores yoru best bet for irradication is manual removal or finding and eliminating the causes.
