Hello, this is a 13 gallon 2.5 year old tank… only pest I have that I know of are bristle worms however I just noticed this attached to the plug of a bird nest coral. Would this be aptasia? And if so how do you recommend I take care of it, the coral isent doing so well so maybe take the whole frag and plug out all together.? Also anyone know what the white tubes underneath the red cap monti are aswell?
