Aggies come in as many color morphs as Pseudotropheus zebra, at least. maybe more. The first ones I owned were plain brownish in the body with brilliant orange tails. At that time (early 80's) there were commonly seen red-tails and purple-tails as well. But over the past several years, as the ful range of the aggie's natural habitat has been explored, multitudinous variations have been found. Bob
