Notes

Celestial Pearl Danios, or CPD for short, are relatively new in the fishkeeping world.  They were discovered in the early 2000’s and were initially called Galaxy Rasboras or Fireworks Rasbora.  They’re super popular for their trout-like spotted bodies and bright orange fins.  For a fish that gets only about 3/4” in size, their distinct features really pop out in a community tank.  A bonus is that they can tolerate a wider range of water parameters making them easy to breed.

Notes

Ember Tetras are very active and social beginner fish.  They schoal in large groups and can tolerate both acidic and low alkaline water conditions. Compare to Neon Tetras, they're smaller in comparison, approximately 1” max.  You’ll find them in almost every local fish store including commercial big box retailers.  You can keep a small community in a 5 gallon tank, but push for 10 or more to see their active behavior. Avoid aggressive or territorial species or large fish with big mouths.

Care

Cardinal Tetras require a more experienced fish keeper.  They’re very sensitive to water changes and require softer to neutral waters.  They’re able to reach 2” in size and the red & blue markings run the full length of their body.  General rule is 2 gallons per fish. 10 Gallon tank at a minimum, but push for 20 or more for healthy and happy fish. Avoid aggressive or territorial species or large fish with big mouths such as cichlids.
