Dwarf Cichlids are inquisitive, brightly colored, small community fish making a comeback in the aquarium industry! 

Cichlids are a group of fish that people misunderstand as aggressive and territorial. This is why some hobbyists prefer them. People blame the Cichlid species for doing aggressive acts such as digging up gravel and plants. Because of this, they are not as popular as their other fish counterparts. 

Fortunately, the Dwarf Cichlids are pretty different from their counterparts. These fish species are not as significant as other cichlids. They are much less aggressive and will live well with other fish species in the same tank.

Another good feature of the Dwarf Cichlids is that they do not require much care as long as you keep them in larger tanks. The fish usually offers fascinating displays in an aquarium setting and great satisfaction with a hobbyist.

  1. Which beautifully colored freshwater fish can you put in the same aquarium without them trying to kill each other off?

    • Hi Diane,

      A number of them are possible with the correct size tank. You could have guppies, endlers and gourami together without any issue provided the tank size is big enough.

    • The biggest challenge is keeping fish with similar water requirements, disposition, feeding needs. Discus have very different needs than guppies. I have German Blue Rams and a Single Gold Ram in a 55 gallon tank with Cardinal, Glowlight, White skirt and Serpae Tetras with no issues. I’m adding Platinum Hatchets after another week of QT. I would never mix GBR’s with Peacock or Flowerhorn Cichlids. Endler’s and Killifish may work. Need to consider the number of fish to make the fish happy as well. Unfortunately there is a lot of bad info out there and I can only speak to my experience. Some fish are just bad actors too. I had a long fin white tetra I got by mistake. I was trying to increase my white skits up to 8 fish and the LFS put one in the bag by mistake. When I added it to my QT tank it went after my new hatchets. I traded him back today for a regular white skirt that is playing nice.

      • Hi Stan, thanks for sharing your experience. I agree with you that we need to constantly ensure that all our fishes are suitable for each other. Flowerhorn definitely an aggresive fish and hard to mix it in a community tank.

        Reply
    • Cichlids — especially the South American ones — are usually very aggressive. Gouramis are mixed in aggression levels. I have had red-fire gouramis that wouldn’t live together (two males) and after re-homing one, the remaining one of them, the the remaining one picked on the cory catfish.

      Honey-fire gouramis are very small and very chill.

    • Hi Maddie,

      You would want to choose fishes that do not nip on your goldfish. Having said that, getting a tank mate for your fancy goldfish can be a little tricky as fancy goldfish tends to be slower thus they will have to compete for food with other fishes. Thus, think twice about getting a tank mate for your fancy goldfish. =)

      Hope that helps.

    • Hi Maddie I also have a fancy tail goldfish (2 actually) and I have a 45 gallon tank.. I have them in with 1 guarami and a couple mollies and a black moore and a pictus catfish and another kind of algae eater (not plucostimus) and a very docile smaller in size beta and everybody seems to get along just fine.. I have had luck with these types for over a year now but all fish are different so I suggest do your homework as to the most docile breeds of fish and I always go toward the smaller in size then my most precious or most docile fish.. good luck!!
