I have a 90 gallon African mixed tank. I'm looking to add some size to my tank and notice lots of people keep fronts in their mixed community tanks. My tankmates get along great. Was wondering if adding a frontosa juvi would be safe. I do have 3 kribs in my tank as well which are about 4-4.5 inches The rest are 5-6 inch Africans. As well as 2 pictus 1 common pleco and a 2 inch Taiwan reef juvi. I was figuring to wait until my juvi Taiwan reef gets to 3 inches just to be safe. How does this sound? If not a front what else could give me a large show community fish?
