How To Care For Celestial Pearl Danio: The Basic Tank Requirements
In this next section, we’ll explain some of the basic tank requirements you’ll need to know when caring for the Celestial Pearl Danio.
The minimum tank size you’ll need to house a Celestial Pearl Danio is 10 gallons / 40 liters.
However, we recommend using a tank size of at least 20 gallons / 80 liters for best results.
Temperature & Ideal Water Parameters
So what are the ideal temperature range and water parameters for Celestial Pearl Danio?
Well, it all depends on where you live. If you live in a hot environment (above 85° F), you’ll need to keep your tank at around 75-80° F.
If not, then a more appropriate range would be 70-75°F.
The same applies to the pH levels of your tank; they should be somewhere between 6.0 and 7.5 if possible!
Ideally, these fish prefer soft water conditions since they’re from Southeast Asia, which has softer water.
Since the Celestial Pearl Danio is a delicate fish, it’s essential to have a good filtration system in your aquarium to keep the water clean and healthy.
A sponge filter or air-powered filter would be ideal for this purpose, as they are both gentle and effective at cleaning the water.
Make sure to change the filter media regularly (every 2-4 weeks) to ensure that your fish are constantly swimming in clean water.
A heater is a must-have for any aquarium, especially if you’re keeping tropical fish like the Celestial Pearl Danio.
The best type of heater to use for this purpose is an adjustable aquarium heater. This type of heater can be easily set to the desired temperature, and it will automatically maintain that temperature without having to worry about it.
Make sure to place your heater in a well-lit area of your tank, as this will help keep the water temperature stable.
Substrate and Decor
When it comes to substrate and decorations for your Celestial Pearl Danio, always keep in mind their delicate nature.
Therefore, it’s best to use a soft substrate like sand or gravel and avoid using any sharp objects ornaments.
Some good choices for substrate and decor would be:
- Sand or gravel
- Live plants
When it comes to living plants, a few are ideal for CPDs.
One of the best plants for this fish is Anubias.
This plant is hardy and does well in low-light conditions. It also doesn’t require much maintenance, making it an excellent choice for busy aquarists.
Another good option is Java moss.
This plant is easy to care for and grows well in many environments. It also won’t tax your lighting system, making it a pretty low-maintenance plant to have in the aquarium.
Java fern is another good choice for Celestial Pearl Danios.
This plant has rhizomes that attach themselves to rocks and driftwood, giving them a secure place to grow.
Diet Requirements and Feeding
The diet for a Celestial Pearl Danio should consist of various foods, including both meaty and plant-based foods.
Some good options for meaty foods would be:
- Mosquito larvae
- Tubifex Worms
- White worms
Some good options for plant-based foods would be:
- Algae wafers
- Brine shrimp pellets
How often do you feed Celestial Pearl Danio?
How often you feed a Celestial Pearl Danio will depend on the type and size of food you’re providing them.
If you’re feeding them small, meaty foods like bloodworms, you can feed them once or twice a day. However, if you’re feeding them larger items like zucchini, you’ll only need to feed them once every day.
We recommend feeding your CPDs 2-3 times per day as a general rule.
The most common diseases that will infect Celestial Pearl Danios are
- fin and tail rot,
- ichthyophthirius (ich),
- and bacterial infections.
Poor water conditions usually cause fin and tail rot.
Therefore, make sure to keep an eye on your fish, do regular water changes (at least 20% every 2-4 weeks), and make sure that the tank’s temperature is stable (~75° F).
If you notice any damage to their fins or tails, it’s a good idea to treat the tank with Melafix or Pimafix.
These remedies are natural and help prevent infection.
If your CPDs start showing signs of ich (tiny white dots on the body), make sure to immediately do a 30% water change and treat with medicine like Quick Cure or Super Ich.
Both of these medications are effective at eliminating the infection.
If your fish starts showing signs of a bacterial infection, you’ll need to increase the water temperature to 86° F and use antibiotics like Melafix or Pimafix.
These treatments will help your fish get better faster, so you mustn’t miss out on any doses.
