you moved your GBRs from the 55 to the 110? thats cool. they now have room for even more of their own kind see if you can get something to clean up algae, such as pitbull plecos (id say get about 5) or otos (get about 6) and something to clean up the bottom. i would naturally go with a Horde of cories. that can be tricky tho, so i dont know. the GBRs normally hate botom dwelling intruders. maybe get some rainbows? bosemani have always been awsome.
