I bought this fish with a same-sized Kennyi about 6 months ago. In the first 2 months the Bumblebee more than doubled its size and turned from gold and brown stripes to mostly brown with only faint light-brown stripes, while the Kennyi grew only slightly. "Seabass" quickly became the largest fish in my 200 liter tank and soon began bullying my Red Zebra, who eventually confined himself to a large shell. I had to separate Seabass so that my other fish could live in peace! Recently I moved my aquarium to my new residence, and I sadly I did not have the appropriate water quality. Seabass swam into a small space and never came out. :(
I have one of these in a tank with two other African Ciclids. He's pretty territorial and won't let the other two anywhere near his holes and caves (which he dug and built himself I might add). Even though it's frustrating filling in his holes so that the bottom of the tank doesn't show through, he's a great fish to have. He's not one to keep with other non-cichlids though. If he gets hungry enough he'll eat a whole pleco and not feel bad about it. He even brings home the skeleton as a trophy. Needless to say I don't buy plecos anymore.
I have a group of 4 crabro and they are gorgeous fish. Very shy and tend to 'peek' over objects to look at you. They grow fairly large, my male is very dark (black and dark blue) and is about 15 cm. The females are about 12 cm and are the traditional 'bumble bee' colour. I haven't been able to successfully breed them yet, my females only hold for about 5 days, so next time I notice they are breeding, I will have to strip her. They love to dig and if you see the male digging furiously, he's getting ready for some lovin'. Mine are in the company of red zebras and there seems to be harmony in this 1.2 meter tank. Buy a few, you won't be disappointed by these gentle fish.
My Bumblebee Cichlid is by far the most interesting and loved fish in my collection. I have had her (Buzz) for about a year now and we've become quite attached. I keep her in a 110 L tank next to my bed. She has quite the attitude at times and likes to play games when the lights go out. She lives alone there because she can be a bit 'moody'. She has killed every pleco I put in with her, and beat the heck out of other Mbuna's I tried to keep as tank mates. She seems happy by herself, eats mostly cichlid pellets and shrimp with the occasional squash slice.
I started off with five of these and let me tell you they are very aggressive! I have given two away and still they rule the tank. I had a Red Devil given to me, she is almost 28 cm and my 9 cm Bumble Bee terrorizes her. He is so much smaller but he doesn't care, he lets her know he is boss. Males tend to be darker than the females, but they both are aggressive. If you are interested in very aggressive cichlids this is one for you. :)
I have two of these in a 540 L tank. Male and Female. As a general rule they get along very well with the other cichlids in the tank, although they have recently started dancing and have become very territorial. To the extent that some of the others are hanging around up the top of the tank to steer clear. I should also mention that they are actually really friendly, and with a week of getting them home they were taking bits of food out of my hand. All in all, I'd recommend them.
