I have put some artificial rock into the tank for the Blenny to hide in as he was looking a little stressed. I have also had to move one of the Blue/Green Chromis's out as he was starting to get a but of a bully
My display tank is currently having some extra holes drilling into the base. It only had one down pipe which meant that it was a little noisy and if it was ever to get blocked then I would be in trouble. I will also be adding an extra section to my sump as its only got 2 chambers. This is the design I will be going for.
