got cha. well I'll give it a try, feed them by hand and hope for the best and see if they have a color morph when they get bigger.
after looking more closely at the rock, there is the cluster on the front like shown in the pic. That front cluster has a total of 9 heads, some are very very tiny babies forming.
On the back of the rock, there is another mini cluster of 4
what is their growth rate and how to they split/multiply?
