keyhole cichlids
yes
easily.. when breeding, fighting for territory.. or if they are aggressive :D you will have to do research to determine what fish are compatible with what.. and individual fish may vary too.. Is your cichlid real calm and passive? then dont put him in with an aggressive fish.. just pick out what fish you want and call your LFS (local fish store) for help.
No, cichlids require lots of space, and they are very aggressive towards other tank mates. If you want cichlids, get a large tank and only put other cichlids in it.
As long as you put in African cichlids with them it should be okay. If you put a south American cichlid, with a African cichlid, they might attack each other because they are not from the same area of the world, and they have never seen them before.
Perona cichlids are known to be aggressive and territorial, so it is best to keep them with other large, robust cichlids in a species-specific tank. Mixing them with other fish may lead to aggression and potential harm to the other tankmates. It's important to research and plan for suitable tankmates that can coexist peacefully with perona cichlids.
Well....yes, you can. But I wouldn't expect to find your other fish in the morning. Your oscar will likely eat them.
It is quite possible that the Convict cichlid would kill a fish as small and slow as a Betta. I would not try to mix other peaceful species with large aggressive fish like Convicts.
Angel fish are types of cichlids and are considered semi-aggressive and often are fin nippers.
When choosing tank mates for cichlids, it's important to consider fish that can handle their aggressive behavior. Some compatible tank mates for cichlids include certain species of catfish (such as plecos), some species of barbs and tetras, and certain types of bottom-dwelling fish like loaches. It's crucial to research each potential tank mate's compatibility and care requirements before adding them to a cichlid tank.
None, you need at least 55 gallonsANS2:A 55-gallon tank would be nice but, you can keep cichlids in a small bowl. The rule of thumb is to not put any more fish in the tank than 1 inch of fish per gallon. Since cichlids like warm water, and since warm water does not hold oxygen as well as cooler water, you will want to reduce the number of fish that you put into a tall tank since there will be less surface area for the water to breathe. Also, you will have better results if your tank has good aeration. When you change water in the tank, avoid changing out more than 10% at a time because the growth of the fish will remain stunted by the buildup of hormones that they secrete into the water. If you change too frequently, the fish will outgrow the tank.
This depends on what type of cichlids you're talking about. The cichlid family is huge and the fish in it range from 2cm to 90cm long. The only cichlids that are suitable for the general community tank are angelfish, apistogrammas and kribensis. None of these should be kept with fish less than 5cm long, and can be territorial and aggressive when breeding. You also need to pay careful attention to how many you put in a tank and whether they are male or female as they will fight if you get it wrong. However they are suitable tankmates for any fish that is large and confident enough to look after itself, such as barbs, livebearers or larger tetras. Smaller dwarf cichlids such as the shell dwellers (Neolamprologus) are not suitable for the community tank because they are too delicate and fussy. Larger cichlids are often unsuitable for the community tank because they will eat tankmates. Most cichlids grow to 15 or 20 cms and need large tanks. Cichlids from the African lakes (Malawi and Tanganyika) can be placed in communities of mixed species of cichlids. These tanks require a lot of maintenance and cleaning because they are usually overstocked to reduce aggression. You do need to be careful when stocking several species from the same genus (ie Aulonocara) in the same tank. They may hybridise and it is very hard (and irresponsible) to sell hybrid fry. You also need to do your research, as although most medium sized African cichlids can be kept in one large community there are some notable exceptions. They will also dig and are not suitable for planted tanks. There are some species that grow larger still. They are sometimes compatible with similarly large and aggressive cichlids if they are not kept with mating partners. If you have a pair of cichlids in the tank, they will see the tank as their breeding territory and may aggressively drive away any other fish. In the wild a pair of large cichlids will take up an area the size of a small room and while they may be perfectly happy and even breed in a much smaller aquarium, they will not tolerate the presence of other fish. Many large cichlids will, however, tolerate a large pleco in their tank. Some large cichlids (such as Uaru) are very pleasant natured and will not attack tankmates. However, they are large and clumsy and intimidating. Others will not eat tankmates but will aggressively chase them out of the way. Finally there are some fish that are just so antisocial and obnoxious you really can't keep them with anything else, unless you're thinking of a tank so large it would not be out of place in a public aquarium.
