Roundtail Paradise Fish (Macropodus Ocellatus) The paradise fish most commonly seen for sale in stores is Macropodus opercularis.
However, there are several other species of paradise fish and all are beautifully colored. The images I included here of the Roundtail are of the male in normal coloration and the much darker breeding colors.
Several years ago, I began with three fish and wound up with dozens. They were difficult to give away here because they are native to the area. However, one friend expressed an interest in taking some of my hands so I gave him a pair and some water sprite.
Just a few days later I got a call. He had been vacuuming what he thought was dirt from the bottom of the tank but discovered instead that they were baby fish.
He had about 200! Fortunately, a company nearby has an artificial pond that contained koi. We asked permission to put the fish there.
To this day you can find paradise fish swimming along the margins and among the cattails.
- Origin: Korea, China, and Japan

They gain better breeding colors when given a period of cold. These fish survive in much more extreme temperatures than their relatives.
They live in areas where the water periodically gets a layer of ice over the top in winter.
Greedily eats any food you give it. They don’t act like a prince. They love to eat whatever you give them.
Provide them with a tank that has lots of floating plants. Do not have strong filtration as they do not like moving water.
Bubblenest builders. The nest is often below the surface and incorporates a lot of plant material so it looks very different from a betta nest.
Females turn almost white during breeding. Males exhibit a higher level of aggression when defending their eggs and young.
Unlike their more common relative, they are able to live in groups without killing each other and can even be bred without separating them from the group provided there is enough room and plenty of floating plants. They are prolific breeders.
