Currently two species f the genus Tanichthys are known in the hobby: the White Cloud Mountain minnow Tanichthys albonubes, and the Jewel Minnow, T. micagemmae. The White Cloud is available exclusively as bred specimens, wheras the Jewel minnows is also imported as wild collected fish. The Jewel minnow has been discovered in 2001 in Central Vietnam.
The maximum size of the Jewel minnow is less than 3 cm, so the species is an ideal fish for the so-called nano-aquaria. Males and females can easily become distinguished by the shape and colour of dorsal and anal fin, which are much larger and more colorful in males.
The Jewel minnow should be kept and bred in schools. The fish are completely peaceful among any other fish. If they are kept in a one-species tank no additional heater is necessary in indoor aquaria. The species spawn in fine plant material. The offspring swims close under the water surface. If the parental are fed properly and with a good variety of food, usually some of the young survive even in the community tank (surface plants are necessary, especially Riccia).
Tanichthy micagemmae is a real gem and every fishkeeper should have tried it.
For our customers: the fish have code 459002 on our stockliste. Please note that we exclusively supply to the wholesale market.
