I know I thought that was a really nice pic of one also,I just realized Haro71888 is probably looking for more info on these so here ya go...
Above: Pseudotropheus sp. "acei," a large captive male photographed by James Stewart; photo used with his generous permission. Up to now, this extremely popular and widely available Mbuna species is scientifically undescribed, so far as I know, and therefore does not have a scientific name.
Superficially, Pseudotropheus sp. "acei" strongly resembles species of the genus Gephyrochromis, G. moorii and G. lawsi, and may be closely related to them. However, "acei" has standard Pseudotropheus outer jaw teeth (stout and bicuspid), whereas Gephyrochromis species have long, slender teeth with a variable number of cusps.

According to Konings (1995c), Ps. sp. "acei" eats algae, like many other Mbuna, but algae from a highly unusual source. It eats the algae (Aufwuchs) that grow on waterlogged wood — logs and tree branches washed into the lake. No other cichlid species is known to exploit this specific food source, which I would suggest could be called epixylic algae (algae growing upon wood). It appears to me to be only behaviorally specialized for this diet, in that it forms aggregations near, and feeds from the surfaces of, the submerged logs and branches. Anatomical specializations for this specific diet, if any, are not evident; the jaws and dentition closely resemble those of many Mbuna that feed on the algae growing on rocks (epilithic algae).
Pseudotropheus sp. "acei" is reportedly restricted to sandy shores on the west coast of Lake Malawi (Konings inadvertently wrote "east coast," but all the localities he cites — Nkhata Bay, Bandawe, Ngara, Karonga, Ruarwe, the South Rukuru River, and Senga Bay — are on the lake's western shore).

Konings (1995c: 246) recognized four geographical variants or populations of "acei," as follows:
Both males and females of the population between Nkhata Bay and Bandawe are blue with yellow fins. This is the variant that was first exported some years ago. The population between Ngara and Karonga is similar except that the fins are white. The trade name for this population is »White-Tail Acei«. A third population occurs between the South Rukuru River and Ruarwe, and in colour pattern closely resembles the fourth population ... found in Senga Bay, and that of G. moorii....
As for reproduction in the wild and in captivity, Konings (op. cit.: 246) stated: In captivity the »Acei« breeds throughout the year. In the aquarium males excavate nests between rocks and are territorial. In the lake males in breeding coloration [which Konings does not describe] are not territorial and do not seem to build a nest. Interestingly, at Ngara

In the aquarium, the graceful, rather elongate shape and beautiful pastel coloration of Pseudotropheus sp. "acei" make it a current favorite, widely available at least in the USA. It attains a length in excess of 4 inches (10 cm), and is not a bad choice for the novice at keeping Malawi cichlids, provided that a large enough aquarium can be used; say, 40 gallons (150 liters) minimum and preferably larger. As already noted above, this species is territorial, at least in captivity, and can be quite aggressive. A single male and three or four females makes a desirable group. Remember that its diet is principally algae, and avoid feeding "meaty" foods such as live or frozen Daphnia, bloodworms, or brine shrimp more than about once a week. Dried seaweed (nori), flake foods rich in Sprirulina, and other green plant foods should be the staple diet. As with all Malawi cichlids, avoid overfeeding and withhold all foods at least one day a week. And, of course, change 30-40% of the water faithfully every week.

Good article but some of the information is incorrect. Acei will get larger than 4" and are often a darker purple than the ones pictures. Mine are dark purple with some iridescent blue high lights and bright yellow fins. Also the article says acei are aggressive which is not true at all. I find them to be one of the most peaceful mbuna out there. They don't bother anyone and tolerate more than one male better than most other mbuna, which is good because male and females look identical. They like to be in groups and will "school" together when in larger groups.
Here's a picture of a couple of mine. The dominant male is the closest. the flash washed out the color a bit.

Here's a few pictures of my new acei's. I've only had them less than a week but they are becoming one of my favorites. The fact that they'll spend some time in the upper part of my tank has made my tank look so much more active and colorful.
I love their color! Deep purple with iridescent blue around the face, adn of course their bright yellow tails.
