Yesterday for the first time my Perc was hosting my RBTA. For about the last year my percs have hosted the frogspawn that is on low and on the far left hand side of my tank. My RBTA is also on the far left hand side of my tank but at the top. My RBTA has been hiding for about a week and I thought it was possibly splitting. No split but it decided to take a walk and come out lower near the frogspawn.... The Percs were lovin it. They went from about 4 heads of frogspawn to a 10" RBTA. YEA!!!! I had given up hope they would ever host my RBTA.
