The Kribensis is by far my favorite fish. Mine are very healthy and have great colors. I have three females and one male in my 58 gallon planted tank. I highly recommend this fish.

As with most cichlids, each specimen is highly variable in personality. When they are sold in stores they are often still juveniles and sexing can be very difficult. For this reason, if fish are overly aggressive toward each other, it is likely that they are of the same sex. Males are usually less colorful than females, and usually have a more rounded and colorful tail. Females are often bright yellow with a very distinct scarlet belly, although males can have scarlet bellies as well. Supposedly they can be harem breeders like most of the dwarf South American cichlids, although this is best attempted in large aquaria. They are very entertaining little fish, and mine have developed such a taste for worms that they will no longer eat flake or pellet foods! They also killed one oto and a hillstream loach so be very wary when combining them with other fish that frequent the bottom level of the aquarium. They get along splendidly with zebra danios though!

Also... Pelvicachromis pulcher is also known as a "Kribensis" or "Krib" not "Crib." This name is derived from a previous scientific name that has been since changed but that has maintained popularity as a common name. Confusingly, the common name "Kribensis" is also commonly used for the more rare-to-the-fish-trade Pelvichachromis taeniatus, but most often it is used for pulcher.

Really a great fish! I just posted a picture of mine guarding their babies. Great parents, and very beautiful fish and do not become overly aggressive to other tank mates, although you may see them get a little pushy when they are with the fry but at most nip a fin of a slow fish that greats too close. They are all around one of my favorite fish and my wife loves them. I have not found that they are easy to find in a LFS

Kribensis is the name that I know it by :) Got my female from a friend that had her in a community tank, she was nipping the fins of that angle fish 0-0. I popped her in a small spare tank with some guppies, no heater, small internal filter. After watching this little fish play Catch the guppies and dart in and out of small rock caves that I will dedicate a tank to a Pair and see if I can become a breeder :) nice looking fish,

Truly one of the best fish commonly available in the hobby in my opinion. They breed easily and are extremely attractive. Also, though they are a chiclid, it is rare for them to mess with the flora.

I keep these and love them, if you keep your water very clean these fish will breed everytime they finish with the last brood. They like to attach their eggs to wood and the female will stand gaurd until they hatch and then continue to gaurd with the help of the male until somewhat mature, make sure to have plenty of good hiding places because other fish will eat the fry. Out of 50 to 75 fry I will usually have 1 to 3 that will survive to adult in a community tank. Although these fish can be kept in a community tank don't plan on having and small creatures like shrimp and other micro type fish as they will get eaten, the males are also good at pulling up carpet type plants.

My contribution will be on how to condition a more peaceful kribensis. I've always found fish raised in the company of other kribs are more aggressive. Frequently breeders keep them in confined tanks where the fish become more competitive and aggressive. If you aquire them younger and raise in single specimen tanks or a single specimen in a community setup(the best option) They are DRAMATICALLY more placid as adults. Every-time I've gotten "killer" kribs they were adults who had spent their entire life sharing a small tank with a couple dozen other kirbs, basically a highly competitive environment. Every time I get a sole baby and raise it in a community tank its is extremely docile. I've done this and combined kribs to get much more peaceful interactions between fish as well. Strange as this may sound its been my experience across the 20 something I've kept since joining the hobby.

I would like to inquire about diet. They are commonly sighted to eat crustaceans etc. I did however find my last pair LOVED to pull algae off of my plants. They would tackle hair algae like nothing else. I've also read that dissections have shown their diet in the wild to be almost entirely herbivorous with soft plant matter and algae making up their stomach contents. Beyond my experience I was wondering if anyone could weigh in on how they would fair with ghost shrimp and nerite snails.

These fish are great. i have had mine for over five years now, although the male sadly passed away recently :( R.I.P They did breed once but sadly the babies were all male. they are a fairly easy fish to breed, but are VERY territorial. They should not be kept with other cichlids as they do not get on. however, when fed with a cichlid diet their colours are incredible! really attractive fish and if bought from a young age as mine were, can make great community fish; as long as others keep out their home patch.

@asimkhatri: mine was a bit aggressive aswell. they may not have paired yet, but sometimes they just are. even after mine had raised a brood, the male still chased her around the tank. i think its possible that he wants to breed with your female, but she is rejecting him. You clould do some research into breeding conditions and see if the female then accepts him. its worth a try as they should calm down.

For tanks smaller than 40 gallons, if you want to add more than 1 Crib, make sure you have the ability to move one out if they don't get along.

What helped my grumpy pair was getting a second pair. They seemed much happier with more company!
