Recently, I have all those fluffy algae cover the rocks and I threw in some blue legs and snails. I didn't have them before so it's helping.
When I ride this out, I will be putting some grasses and algae that the foxface won't eat.
Originally this was supposed to be a completely dedicated aquarium, but I put that foxface in to help me out with the algae and he wiped them all out so I have to start over.
I want to add that I'm not satisfied with the way things are and how they are looking. The tank is 150 gallon cube and I hope that blue one bounces back. I moved them from an Elos sytem 70 to this cube and was very nervous about the transfer. I still am and hope they don't decline.
