- Be Patient: Breeding Celestial Pearl Danios can be a bit of a waiting game. It may take some time and observation to understand their breeding behavior fully and fine-tune the conditions for success.
Personal Perspective
Celestial Pearl Danio is a favorite nano fish in the home aquarium. I believe these little guys have some of the best personalities you can find in a nano tank. They remind me of super small red-bellied Sammon, but small enough to fit in any sized aquarium. I have noticed that they do best in large groups; for this type of fish, I would recommend having at least 12 of them. The rule of thumb is the more you have then the more you will see of the fish. You will also be able to enjoy more of their natural behaviors in a larger school. Now, if you were dead set on only having something like the size of them, I have noticed that if you get other types of schooling fish around their size, it will help the CPD feel more comfortable and come out to feed/play more often. If you don't get them in a big school, these guys will almost always hide any time they come across a larger fish or if you ever approach the tank. We all get these wonderful fish specifically so we can see them! In my experience, I would really recommend mixing them with emerald rasbora, ember tetra, or chili rasbora. They all get around the same size and can mix their schools without much stress.
I have also noted that these are some of the easier fish to care for. They have an acceptable wide PH range and other water parameters. These guys could even do well in a tank with no heater as long as you keep your home warm in the winter. They don't need a large tank, so space is almost never a limit for their happiness. They will eat almost anything and are generally aggressive feeders, so you won't have to worry about any other aggressive feeders getting the food before they can get a bite. I have seen that these guys are most interested in grabbing the food directly from the water column, but if a larger piece gets caught at the bottom, they would be open to grab a bite.
If you find yourself interested in breeding and want to take the next step above livebearer fish, these would be your best bet. They only need some soft plant-like material like moss and good tank parameters. They do a little dance on top of it, drop some eggs, and fertilize them as the eggs drop to the bottom of the moss for protection, and I know they need it because, given the chance, they will predate their own eggs and fry. The fry, for the first couple of days, will not move much, which would make them extremely easy to pick. So, I normally place the moss in a plastic container and check for eggs every three or so days. Then i raise the eggs in another tank where they would be safe from predation. This is so much easier than letting the parents lay eggs and then net out all the fish in the aquarium like you need to do for other fish species. This is also beneficial because the parents typically only lay a few eggs at a time, unlike some other species that could do hundreds at once.
So overall, I think these nano fish would be a great addition to any peaceful community tank you have.
