Ya I've been needing to do that just looking for placement on each of them. Thanks!They are common gobstoppers and their discharge habit is common. They do this more when under high nutrient conditions or when adapting to different tanks. They do look like they need more light.
There are really too many different kinds on that rock, and being tall growers the gobstoppers will likely bully the rest, especially the utter chaos in the upper right that don't like to fight for territory. When things get all established you might want to frag some off the rock so they can all have room.
