good thinking - a nano tank for zoos
I have to test out my convincing power ...
BTW, my fish did not pick on every colonies. I have one that started with 30+ polyps and now the rocks have more than 100. One rock that started with 100+ ended up having only 3 left after a couple of days... that 3 now have multiped to 15
... hopefully more ... I also had one rock that the fish got every single polyps.
