First and foremost, you need to make sure that the fish you choose are of similar size. This is important because if they are not, the larger fish may bully or even eat the smaller ones.
Secondly, you’ll want to pick fish that have similar water quality requirements as CPDs. This means choosing fish that can tolerate slightly warmer water temperatures and prefer a well-oxygenated aquarium. With these guidelines in mind, here are some great options for tank mates for your Celestial Pearl Danios:
Tetras: Tetras are a great choice for tank mates because they come in many different sizes (so you can find ones that match up well with your CPDs), enjoy warm water temperatures, and prefer an oxygen-rich environment. Some popular tetra species include neon tetras, black skirt tetras, and bloodfin tetras.
Barbs: Barbs make good companions for CPDs because they too come in a variety of sizes so you can find some that will be just the right size match.
They also do best in warm water conditions and tend to like being in groups (so your CPDs won’t feel outnumbered). Common barb species include tiger barbs, cherry barbs, and gold Barbies.
Gouramis: Gouramis share many similarities with Danios when it comes to preferred habitat and water conditions so they make natural allies in the aquarium world.

Will Emerald Dwarf Rasbora Eat Shrimp?
There are a variety of factors to consider when wondering if Emerald Dwarf rasbora will eat shrimp. The size of the shrimp, as well as the size of the fish, is important to take into account. It is also necessary to consider whether the shrimp are alive or dead, as this can make a difference in whether or not the fish will be interested in them.
Generally speaking, Emerald Dwarf rasbora are not likely to eat shrimp that are smaller than they are. This is because they typically prefer prey that they can easily swallow whole. Shrimp that are too small may be ignored by the fish or even rejected outright.
Additionally, larger shrimp may be seen as a threat by the Emerald Dwarf rasbora and avoided altogether.Live shrimp will usually be more appealing to Emerald Dwarf rasbora than those that are already dead. This is because live prey tends to put up more of a fight, which can make it more interesting for the fish to chase and capture.
That being said, there have been reports of Emerald Dwarf rasbora eating both live and dead shrimp, so it ultimately depends on the individual fish’s preferences.
How Many Dwarf Rasboras Can I Put in a 10-Gallon Tank?
Assuming you are talking about the Dwarf Rasbora (Boraras brigittae), also known as the Redfin or Nano Rasbora, the short answer is that you can keep 8-10 in a 10 gallon tank. The long answer is a bit more complicated though, as there are several factors to consider when stocking any fish tank.The first thing to think about is water quality.
These little fish are very sensitive to poor water conditions and will not do well in an aquarium that is not properly maintained. This means regular water changes, filtration, and keeping an eye on things like ammonia and nitrite levels. If your tank is not properly set up and maintained, it’s best to err on the side of caution and stick with fewer fish.
Another important factor to consider is diet. Dwarf Rasboras are omnivores and need a variety of both meaty and plant-based foods in their diet. A good quality flake or pellet food should form the basis of their diet, but they will also appreciate live or frozen foods such as brine shrimp, daphnia, or bloodworms.
Be sure to offer them a variety of different foods to ensure they are getting all the nutrients they need.When it comes to tank mates, dwarf rasboras do best with other peaceful fish that are roughly the same size. Good choices include other small rasbora species, guppies, platies, tetras, etc.
