The aulonocara peacock cichlid aquarium
If you have previously kept a Malawi cichlid tank and want a change or are considering setting up a new one, then you may consider setting up a peacock cichlid aquarium. Rather than having a wide range of species from lake Malawi, concentrating on just peacocks will give you an aquarium full of colour. The most remarkable fish from lake Malawi are the Aulonocara species, commonly known as peacock cichlids. There are 22 different peacock species known at present – all with brilliant colours.
Types of peacock cichlid aquariums
There are three basic choices when it comes to setting up a peacock cichlid aquarium. Each of the following three choices comes with specific advantages and drawbacks:
- All-male tank
- Mixed species breeding colony
- Single species breeding colony
Understanding which of these three options suits you best requires you to identify your main goal with the tank itself. If brightly coloured fish is your only consideration, then an all-male tank would be ideal, provided that your tank is large enough for them to create several distinct territories. An all male tank means choosing male peacocks from several species. An all-male tank precludes your fish breeding. The all male aquarium is a display aquarium.
Single species and mixed species peacock cichlid aquariums
While an all-male tank is certainly the simplest and most colourful option, breeding is one of the most fascinating behaviours that peacock cichlids engage in, and creating the right environment for them to do so, will be hugely rewarding. A single species tank is the simpler of the two, since you will not have to deal with inter-species aggression or interbreeding. You can also get away with a smaller aquarium, but it will be less interesting. And you have the further problem of choosing which single species to include in your aquarium.
Just like the peacocks they are named after, you will find that the females of any of these species are less colourful than the males. While it may be tempting to add more males than females to your setup, this is unnatural for a peacock cichlid colony and will result in stress and territorial disputes. The ideal distribution is one or two males with a larger group of females, perhaps 5 or more females.
One of the benefits of a single species breeding tank is that you can turn it into a breeding colony that lets you examine and observe the entire life cycle of your fish, their fry, and later descendants as well. By keeping a single species of peacock cichlid in your tank and taking good care of them, they will be able to raise some fry naturally without requiring you to set up separate breeding tanks and raising the fry yourself. However, to maximise the spawn you will need to remove the fry or brooding male to another tank.
The mixed peacock tank allows you to create a biotope of lake Malawi. Mixed species tanks, however, are not likely to make efficient breeding colonies because of interspecies competition. Your choice of species for this kind of tank will have to be carefully chosen in order to minimize stress, aggression, and the risk of interbreeding.
Choosing aulonocara peacock cichlid species for a mixed tank
If you would like to enjoy the multiple colours and differing behaviours of peacock cichlids in a mixed species tank, you will have to choose species that can get along together. Luckily peacocks are less aggressive than mbunas so you have a head start. The males are usually only aggressive when defending their own territory. The key to choosing your selection of peacock cichlids is in choosing species with a wide variety of colouration: Different species with similar colouration will see one another as breeding rivals, which will cause fights and interbreeding.
Size can also play a role in interspecies aggression between these fish. Species such as the peaceful Long Nose Peacock (Aulonocara Rostratum) are significantly larger than most other members of their species, for example. A fish of this size is unlikely to view a much smaller specimen such as a Ruby Red Peacock (Aulonocara Rubescens) as a threat. In fact a single, large male may become, “king of the tank” and settle disputes between the other fish as well.
Varying the fish sizes can also help ensure that interbreeding does not occur. Females of all the Peacock cichlid species tend to look similar and may mate with dominant males of other species to create hybrid fish. Hybrids are generally undesirable and should be avoided if you would like to maximize the colouration and good health of your fish. A mixed tank featuring fish with greatly varying colours and body size will help reduce the risk of interbreeding. For example where the female of one species is brown and the female of the other species is silver then interbreeding should not occur.
When choosing which species to place in your aquarium you should remember that each species has several colour variations depending on which part of lake malawi they come from. Having different colour variations of the same species will result in interbreeding.
Peacock cichlid care
Once you have spent some time researching which fish and set up you want, you will want to spend some time researching the aquascape that your fish will be living in. The more accurate and natural-looking the environment for your fish, the less stressed will be your fish in the long run. For peacocks, there are two basic choices of aquarium layout either a sandy area or a rocky area with caves. In a larger tank you can of course have both.
Making the environment work requires researching into the origins of your specific species. For a single-species tank, obviously, you should attempt to replicate the original environment as close as possible. For a mixed species tank, however, you may need to provide a kind of hybrid zone for the separate territories of your fish.
“Jakes” of the species Aulonocara jacobfreibergi, for example, are primarily cave-dwelling fish that prefer rocky aquariums with lots of hiding spaces. Mixing this species with a sand-dwelling northern peacock ,such as Aulonocara stuartgrantii, might be a poor compromise, unless you have a large enough tank to provide two large zones within the tank for each of them to inhabit. In fact, it is recommended that any mixed species tank be as large as possible for this reason.
If you have followed the above guidelines, you should have a successful peacock aquarium. The various species of peacock will peacefully co-exist in the aquarium without stress. This will enable the male peacocks to display their best colours with fins proudly spread. When this has been done properly, you will have an aquarium that will rival a typical marine aquarium for its beauty and colour. The reds of the rubens peacock, the blues of the stuartgrantii peacock and the yellows of the baenschi peacock will give a brilliant contrast of colours. Sit back and enjoy your fish with a sense of pride.
