They're Pseudotropheus socolofi. Malawi Mbuna. They should go pretty well with the labs. I considered them for my 55g Malawi setup.

They are Albino socolofi, and are hybridized to get thier albino color. They are mostly socolofi genes though, so i wouldnt worry about mixed behaviour. I think they are pretty peaceful and should get along with Labs no prob. You can probebly fit 3 or 4 more mbuna, depending on the species.

Providing you set your tank up with enough rockwork, you should be able to keep 20 or so full-grown malawi cichlids in your tank. I would avoid the fish that get bigger such as Venustus. I have a 75 gallon mixed african cichlid tank with 30+ fish and it has been going for about 5 years.
As far as adding plecos goes, I would avoid putting them in the tank and opt to buy some Synodontis catfish as your clean up crew and use a magnet to keep the glass clean. Your fish will graze on the algae growing on the rockwork and your gravel shouldn't get too dirty from frequent water changes.

Fishseller, the reason overcrowding works in your tank is because its a large tank. I would not reccommend to overcrowd your cichlids in ANYTHING under a 75, there is just not enough 'escape room'. Also, heavy filtration and proper species selection is a must.

I think having a few groups of 3 or 4 cichlids is just right. That way, you can add some bottom feeders like some syno cats and a pleco (bristlenose are the best, they stay small and kick butt on algae). If you like the socolofi and yellow labs those will be fine together. If you wanted peacocks though, the only mbuna i would keep with them are yellow labs and P. acei for beginers. You could try different species, but diet and aggression really need to be considerd because peacocks eat and behave differently than mbuna. The socolofi might be ok, but they are more vegetarian and a little more aggressive.

Do things slow, and you should be okay. Add all the fish when they are young and grow them up together.

I agree wholeheartedly with Diana's comments about overcrowding. I really works in tanks 75+ gallons. Anything smaller than that and there's just not enough swimming room to allow attacked fish to escape.

The only suggestion would be to grow the smaller ones up a bit in another tank. They dont have to be the same size when added, but as long as they are big enough that the other yellow wont eat them, and there are lots of hiding places, it should be fine. If you can, add the small ones to the big tank first, and then a week or so later add the larger yellow lab. That will give the smaller ones a better chance.

If you can find other hobbyests or breeders in your area (via online groups) then you have a better shot at getting larger fish.
