I have a 255 gal display about 325 gal with the sump. Current fish list is coral beauty, 2 clown fish melanurus wrass, Christmas wrass, yellow Tang, timini and bristle tooth Tang. Some one locally is breaking down there tank and I was looking at adding 4 lyretail anthias, fox face and sailfin Tang. Will this be to many fish and will I have problems adding the sailfin? Have had the yellow Tang for a couple years the other two tangs were added in April.
