Celestial Pearl Danio (Galaxy Rasbora)

The Celestial Pearl Danio (CPD) also known as the Galaxy Rasbora is one of the most popular nano fish available to hobbyists today. It is one of our favorite fish at Flip Aquatics as well. The CPD is striking in any planted aquarium with a unique look with vivid red fins and yellowish white spots on a bluish colored body.

Please Note: All fish shipments have a 100% Live Arrival Guarantee when shipping wit Overnight (1 Day) option. All other options void our Live Arrival Guarantee for fish. 

While the small size of the CPD might make it seem compatible with other fish of the same size, they are often very shy and can be easily out competed for food. It is recommended to pair this fish with bottom dwelling catfish or surface swimming fish for the best results.

The CPD reaches sizes between ½ inch to ¾ inch.

The scientific name for the CPD is Celestichthys margaritatus.

We feed our CPD’s a mix of frozen foods including daphnia, baby brine and cyclops. We occasionally feed them Northfin Veggie. They will accept live foods if prepared.

Pearl beauties

All fish arrived alive and in good condition, nice size and good color. Doing well in my tank! Our local store recently closed; I think I have found my new source for quality healthy fish!

Great healthy fishes

Amazing packaging. The fishes arrived healthy and I received an extra CPD. They were quite bright and colorful when they arrived. Great to look at and they are super active. They have left my red cherry shrimps alone and they don't bother anyone besides each other. YMMV


They were delivered healthy and alive also one freebie. Amazing quality thank you!


The fish arrived healthy looking and spear to be coloring up after only a week. Going 6 months since I bought chili rasboras. There are thriving are are a bight red. Beautiful

Little beauties

The CPD’s arrived in great health and size. Really pretty and while only two weeks since I got them, they're showing no signs of illness. I’ll be taking these out of quarantine sooner than expected. Awesome service and help from the folks at Flip, thanks!!
