Here is what they look like now, they were small when i got them but they are in between micro and regular sized polyps. I love the yellow speckled centers.
Our club tried a growout competition with these or maybe a nearly identical zoa. I'm not sure anyone was successful keeping them....mine melted pretty quick, others grew from the single poly to 5-6 and then melted.
Wierd! Yea thats what was happening to us. Hopefully its gotten used to the system by now and can grow. I have a frag in a tank i set up at my buddies house who is running biopellets and his frag exploded with polyps so i have my hopes up now. But in the beginning the original rock in the pic had to be cut up. Zoas kept melting so i ended up with 3 or 4 one polyp frags. From the rock. One polyp made it thank god.
