I have had one of these fish for over a year now. He loves to dig down to the bottom of the tank, under the plastic rock sculpture that we have in the tank. I think he digs down so he can see himself in the bottom glass (*wink*). This fish does not take no bull from any fish! He has had several roommates that have had to abandon the tank for fear of this blue monster we have nicknamed 'Bulldozer'. Don't worry, the abandoned fish now have happy new homes of their own.
I have five of the little fish and, while I agree with pretty much everything the others have said, I think there are better pale blue fish of similar temperament. I also think that this is a fish that has been bred intensively to their detriment and the group that I bought were really difficult to sex. The colours, while nice, are not as intense as say Maylandia estherae or callainos. A good male specimen of either of those two are just spectacular - they just bristle with character and the colours glow. However, my dominant male socolofi is neat and doesn't take anything from anyone without being proactively aggressive. I suspect they are a bit 'nippy' - all the socolofis fins are always ragged in contrast to the other species I have. Usual Mbuna recommendations apply - loads of vegetables, especially chopped peas, sometimes a little chopped shrimp (I mean a little - maybe once a week), a spirulina enriched flake or pellet, tons of rockwork, regular water changes and these guys like all mbuna will charm your sock off.
I think that the socolofi is one of the greater looking cichlids. They are an awesome powder blue and are very aggressive. I have a total of three socolofi's in my 200 liter cichlid tank. One of them (her name is "the be-yatch" because she acts like one) is two years old, already 10 cm and very healthy. She kicks everyone out of her log and chases our convicts and bigger venustus around the tank. She's not scared of anyone. Also, when we clean and redo the decoration, she's the first to find a new home and claim it. She likes to move gravel too and gets along with all our cichlids. I recently bought her two more friends, which were also socolofi's and about 4 cm big (babies). They are currently doing fine and they only hang out with our other baby cichlids (haplochromis, ahli, blue regals, and compressadoris). As for the "be-yatch", she only hangs with the cichlids her size, and she doesn't pick on the babies at all.
I have 3 of these very active fish, 2 females and 1 male. Talk about fish that like to breed. I have had them since they were 3 cm long. Three months later I had 11 babies from 1 female. Two weeks after that 22 fry from the other. That was 2 weeks ago and the first female looks ready to lay eggs. I have them in a 200 liter tank with other mbunas. The male socolofi is the king of the tank, nobody messes with him, not even my 3 large female red zebras, and they are twice the size. I would strongly recommend them to anyone who likes cichlids.
I have one of these guys in my tank. When he was young, he was peaceful as can be, but as he matured, he aggressively attacked everything in the tank: both the cray and the eel had to get new homes with my friends. He rules all the caves in my tank, and chases the algae eaters, just to show them who's boss, I think. All this, and he's still only half grown! If you're looking for a peaceful fish, turn away from this one.
I have 3 of these fish. They seem to be very aggressive, the dominant fish has managed to 'take out' two Demasoni and another Socolofi, and is hard at work on another Socolofi. I have tried splitting them up, but the other two then go at it hammer and tong. The color of my Socolofi range from a very pale blue, and pale blue with grey barring and yellow with almost white patches. I'm almost sure the non-stop fighting is having an adverse affect on the coloration. I love my fish, but they are a complete pain in the ****!
