Tank Mates

Cardina and Neocaridina shrimp, Tetras, Rasboras, Danios, Hatchetfish, Mollies, Dwarf Gourami, Angelfish, Guppies, Loaches, Otocinclus, dwarf shrimp and snails

Notes

Bloodfin tetras can be both subtle and vibrant.  Their silver bodies and red highlights make them great community fish.  General rule is 2 gallons per fish. Provide a minimum of 10 gallons, but aim for 20 to provide extra room to swim.  Avoid aggressive or territorial species or large fish with big mouths such as cichlids.

Paracheirodon axelrodi

Characteristics:

Tank Mates

Tetras, Rasboras, Danios, Hatchetfish, Mollies, Dwarf Gourami, Angelfish, Guppies, Loaches, Otcinclus, dwarf shrimp and snails

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.

Hyphessobrycon pulchripinnis

Characteristics:

Tank Mates

Tetras, Rasboras, Danios, Hatchetfish, Mollies, Dwarf Gourami, Angelfish, Guppies, Loaches, Otocinclus, dwarf shrimp and snails

Notes

Lemon Tetras have vibrant fins and a more flat, diamond shaped body.   They're very active swimmers, so a 20 gallon tank would be ideal for a group of 6 or more.  Avoid aggressive or territorial species or large fish with big mouths.

Melanotaenia lacustris

Characteristics:

Tank Mates

 Cherry Barbs, Tetras, Rasboras, Danios, Dwarf Gouramis, Hatchetfish, Mollies, Guppies, Plecos, Dwarf Corydoras, Loaches, Otocinclus and even Dwarf Shrimp.

Notes

Also known as Lake Kutubu Rainbowfish or Blue Rainbowfish, Turquoise Rainbowfish are simlar Boesemani Rainbowfish and are peaceful middle-top dwellers with small mouths.  They do well in a community with many nano fish including cherry barbs.  Minimize plant and decoration density and aim for 48" long tank to give them ample swimming space.

Danio margaritatus

Characteristics:

Tank Mates

Tetras, Rasboras, Danios, Hatchetfish, Mollies, Dwarf Gourami, Angelfish, Guppies, Loaches, Otocinclus, dwarf shrimp and snails

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.
