So my stubborn zoanthids look like they're finally opening. However, it looks like it's not open all the way, or they are skirtless. Is there such a thing as a skirtless zoanthid? Will they grow it later or something?
I have never seen "skirtless" zoas, but i have seen some, especially like paly's that have little nubs all the way around the edge of each polyp as opposed to the extended "fingers" found on most skirts.
I would say give it some time, put them in an area where there is some current, and see how they look in a few days.
ive just counted again and when i got my branch about 4 months ago there were 6 zoas... now over 24.... tripled in that time... that means in 4 months ill have close to 100 spreading all over that side of the tank...
