How many

What about electric yellows? Could they get along with keyholes...? Or do they need to be alone.,.and if they need to be alone...how many could I have in a 29g?
 
Yellow labs need a very different water chemistry and diet than the keyholes.

Like i've said many times before, you can get about 3 yellow labs in that tank, but nothing else. They really should have a bigger tank but 30 gal is bare minimum so you might be ok. They need a pH of about 8.2, moderately hard water, temp of about 78F.... sand substrate and lots of rocks. You might be able to keep some plants in there with them if the plants will handle the high ph and taste bad to the yellow labs (ie- valliserneria, java fern, anubias).

Listen to "Love my kribs" you can put some awsome fish in that tank, but you can't mix African and South American Cichlids (besides water chemisty the "look" of the biotope is way different). If you want to keep multiple species your best bet is SA.

Pick your favorite looking dwarf cichlid, and get one male and one, maybe two females. Then pick some cool "support fish" (my name for dither fish). A trio of cories, small school of hatchet fish for up top, a pair of ottos for algae, and some tight schooling tetras (black). The tank will be dynamic, biotope accurate, and just look plain awesome.

I was in search of the "multiple cichlid species in a 29g" dream not to long ago also. It's just hard to realize, and when I did the tank looked disorganized.

With that said, if you gotta mix cichlids you at least have to stay on the same continent.
 
Not responsibly. The yellow labs are rift lake cichlids from Africa (harder water), while the convicts are new world cichlids (softer water). Also if either pair starts to breed (the convicts will for sure) they will become violent toward all other fish in the tank.
