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.

Paracheirodon innes

Characteristics:

Tank Mates

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

Notes

Green Neon Tetras are great beginner fish.  They're similar in appearance to Neon Tetras except their red color is very faint and their green/blue-ish stripe is super vibrant.  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.

Pethia padamya

Tank Mates

Active and fast swimming community fish like Zebra Danios, Cories, Loaches, Platies and Rad-tailed sharks.

Avoid slowing moving, long finned fish like Bettas, Guppies, Gouramis, dwarf shrimps and small snails.

Notes

The Odessa Barb can be aggressive with other Odessas in the same tank, particularly the males exerting dominance.  They may also nip at slower moving fish or fish with long-flowing fins, such as Guppies, Angelfish, Betta fish, Goldfish, Gourami and small snails.

Hyphessobrycon herbertaxelrodi

Characteristics:

Tank Mates

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

Notes

Black Neon Tetras are slightly larger than Neon Tetras and are great beginner fish.  The reason is because they can tolerate both acidic and low alkaline water conditions. This makes them hardier than Cardinal Tetras and a bit easier to keep.  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.  Black Neon Tetras are generally more confident and you'll find them swimming near the top than hiding.

Melanotaenia boesemani

Characteristics:

Tank Mates

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

Notes

Although larger in size, Boesemani Rainbowfish are peaceful middle 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.
