I bought a ric, my first ric, at the fall frag swap in September. It hasn't split yet. I have been debating cutting it in half, but I worry that it will melt if I do cut it in half. So far me so far, they have been a very slow grower.
I will also add that I feed it spectrum pellets about once a week. I don't know if it helps at all or if it can even process them, but it does eat them. I also add oyster feast twice a week.
Im with KilaGo. I used to have a ric garden in my last tank, and I fed them pellets and they sprouted mouths MUCH faster than before I did. They usually develop many mouths, and then split.
