You can probably add Electric Yellow Labidochromis (yellow labs)
My breeding colony of E. Yellows lives in a 29gallon and doesn't eat their babies for the most part, which is almost unheard of when it comes to cichlids.
Kenyi <- one of the most aggressive African cichlids, will eventually kill everything,
Labidochromis <also known as yellow labs. This would be my first pick and shouldn't be problematic
Jewel <- an african that looks and acts like a south american, tends to be real MEAN
Ahli, < this is a member of the HAP family, they tend to be better behaved them most mumba's but i have not personally kept the electric blue so i can't give first hand exp. If you love them you can try them, for the most part Haps get bullied in my tanks, so he may be an ok fit, but if he turns out to be a serial killer.... well....
Zebra<- Sassy little buggers, likely too aggressive
Bumblebee< these get a big too large for what you already have and tend to be a bit on the sassy side too. I kept a 1" Bumblebee in a tank of fish that were all 3+" and he never got messed up, nor did he hide all the time. That being said your tank isn't currently aggressive enough to take this guy on.
Auratus <- so mean it would take on a fish twice it's size for fun, not joking! Chipoke are a similar fish with similar issues.
Acei <- I like these and this would be my second pick behind the yellow lab. They are known to be peace keepers, and have been known to break up fish fights between other fish
The above fish are lake Malowi African cichlids, they tend to be smaller and nicer then their south American/central American cousins.
Green Terror <- south american going to get BIG and mean,
Managuense <- also known as the Jaguar. south american going to get BIG and mean
Midas <- south american going to get BIG and mean,
Red Devil <- south american going to get BIG and mean
,
Jack Dempsey<- south american going to get BIG and mean,
Blood Red Parrot<- ok, so what you need to know about these is that they get big, and they are sassy. They generally can not close their mouths all the way, and when you start out with them they are very timmid, in the end they are south american and still going to get BIG and mean
Black Convict <medium sized and mean,
Turquoise Severum <- south american going to get BIG and mean
Firemouth. <- south american going to get BIG and mean
Hopefully that helps. I would add a trio of electric yellows with out hesitation to your tank.
