Cichlid issue

Question
QUESTION: I have a 60 gallon tank with a mbuna, peacock and hap mix. The fish in the tank our as follows, 2 bumblebee, 2 livingstonii, 2 red top zebra, 1 red zebra, 1 kenyi, 2 yellow lab, 1 ob peacock and a venestus. I recently added the venestus. My question is this are venestus much more timid than the livingstonii. No matter how often I change the tank around the venestus still cowers. It consistantly hides behind the filter. I've had the Livingstonii for 4 months. I've never had an issue with the livingstonii they get along great with the other cichlids. I have 2 questions? Is there anything I can do to accomodate the Venestus and are the Haps going to get too big for this tank?

ANSWER: Hi Doug,
The Livingstoni is a predator.  As he gets older, he often plays dead to catch smaller fish.  He should be in a tank with at least four females.  They need lots of room to swim, sandy bottom, plants, and wood.  The venestus is similar to the Livingstoni, and grows to 10 inches.  He too must have at least four females.  They will outgrow your tank.  They are agressive towards their own species, and will not hesitate to kill any other male of their species.  The Livinstoni, and the Venestus do not get along.  There is nothing you can do about this.  The Venestus if smaller than the Livingstoni is afraid of him at the moment, and with reason.  These fish get along with other species, but not with their own.
The Kenyi cichlid is very aggressive, and as he grows older will become more, and more aggressive.  He is best kept with Mbunas, fish of his own species.  He grows to 6 inches, and needs lots of room to swim.  
I hope this helps

QUESTION: You talk about the Kenyi aggression. I really don't see it. Is it because it's a female. The most aggressive is a toss up between the bumblebee, ob peacock and for some reason the so called timid yellow lab male. Is it normal for a yellow lab to be very aggressive. He's very territorial. Also the male OB peacock forced me immediately to bring the 2 other peacocks that I bought back to the store. Why are OB peacocks much more aggressive to peacocks and not Mbunas? Aren't they a combination of both.

Answer
Hi Doug,
Kenyi's have been bred so much with other mbunas, that you never know for sure if you have a pure Kenyi, or one that as been interbred, unless you know the breeder.  With African cichlids, you can never be absolutely sure.  Kenyi's are aggressive, whether male or female, and should be kept with other Mbunas.  When young the Kenyi will be less aggressive, but you will see, as he grows older he will become more, and more aggressive.
The yellow lab is less aggressive, and should be kept with other african cichlids of the same species.  My guess would be that your yellow lab is aggressive because he is afraid.  There are always some exceptions.   Keeping African cichlids, takes lots of observation.  Why one fish is more aggressive than the other, I really do not know, since each fish has his own character.  One fish can be the exception to the rule.  Only you can see what is going on in your tank, and you must observe them very carefully.
When keeping African Cichlids, it is best to keep only females to one male.  Males will kill other males, so you must go by the book.
 Mbunas should be kept with Mbunas.  Peacocks are much less aggressive, and should not be kept with Mbunas, however, males will be aggressive towards other male peacocks.  This is true of most African Cichlids.  
I hope this helps.
