Trigonostigma somphongsi (Siamese Dwarf Rasbora)

Formerly known as Rasbora somphongsi, this microrasbora is an extremely rare, beautiful and peaceful little fish that would be an amazing addition to ones tank- especially those with nano tanks.

Also known as the Siamese or Somphongs's Dwarf Rasbora, this is an extremely rare microrasbora that is native to Thailand. It is can be the highlight in any peaceful community aquarium and it is a particular standout in any planted aquarium.

With optimal diet and care, many within this species display a beautiful orange coluoration, especially in males.

It is the smallest member of the Trigonostigma genus (which also includes the beloved Harlequin Rasbora). This species is unfortunately critically endangered due to habitat destruction in the wild, but it is bred by a few breeders around the world.

Typically occupying the top and middle level of the water column, the Siamese Dwarf Rasbora can often be seen swimming and feeding in the middle and bottom levels as well. It is safe to keep with other peaceful, small fish, but it is easily intimidated so tankmates must be chosen with care. Due to its extra small size and peaceful demeanor, a suggestion may be to keep them with dwarf shrimp.

Fish information (behaviour and breeding):

These fish enjoy feeding on small insects, worms, crustaceans, and other zooplankton in nature. They are easy to feed as aquarium fish, but to in order to achieve the best colours, offer regular meals of small live and frozen foods such as bloodworm, Daphnia, and Artemia, alongside good quality dried flakes and granules.

This species seems to do best under fairly dim lighting. Remember to find plants which thrive under those conditions from genera such as Microsorum or Anubias.

The Siamese Dwarf Rasbora spawn on the underside of broad plant leaves and although they prefer to live in schools, if you choose to breed them, be aware the spawning pairs most often separate themselves from the conspecifics. The males even defend a small spawning territory for a short time. V-tanks are ideally suited for the extensive breeding of this species. Here young fish can be usually separated on a regular basis.
