I wanted to keep some GSP from taking over my tank so I made a pillar with the GSP on top and placed some zoos around the base. Now the GSP has started to creep down the pillar and I need to know if the zoos can fend off the GSP or if I should try to move them to a safer place. Here are a couple of pics:
And a close up of a zoo sort of leaning away from the advancing GSP.
So what do you think? Will the GSP overrun the zoos or will they fight back?
