Wow very nice goby peaceinusa!
I haven't noticed any fish resting on it, I only see the usual trying to get pods occassionally. I haven't moved the colony or changed lights. All the lights are on timers, day to dusk thing, so lighting is very consistent. The coliny is in the open so nothing shadows or even touches it. I attached it to a tonga branch to let it spread just on the branch. I swished water on the gsp to remove some of the junk that had collected on it. It is still closed for now I will keep an eye on it and see how it does and hopefully all will be fine in a few days. Thank everyone so much for their insight.
