*Work in progress*

Scientific Name: Hemimyzon formosanus (Boulenger, 1894)

Common name: Unknown

Synonyms: Homaloptera formosana Hemimyzon formosanum

Distribution: Taiwan

Sexual Dimorphism: Unknown.

Maximum size: 4 inches (10cm)

Similar to: Other Hemimyzon species

Care: Inhabit fast flowing highland streams over boulders. Aquarium must duplicate these conditions as fish have very high oxygen requirements. See Hillstream Loaches: The Specialists at Life in the Fast Lane for more detailed explanation.

With all sucker-type Hillstream species, care is broadly the same. All need excellent water-flow and aeration, numerous rocky hiding places and smooth pebbles and boulders to graze over. Lighting should be bright to encourage algal growth in the aquarium. Plants are not necessary as the fish do not normally encounter them in the wild, but they will help with water-quality. Suitable plants for high-flow environments are Anubias and Microsorium. These will grow on rockwork or driftwood.

Feeding: The diet in aquaria probably consists mostly of bloodworms and brine shrimp as well as some algae and prepared foods.

Water parameters: pH:7.0-8.0 Hardness: Medium Max dh:

Temperature: 68ºF to 75ºF(20-23.8°C)

Breeding: Not bred in aquaria.

Notes: Hemimyzon formosanus is not well known in the pet trade but may show up as a contaminant in shipments of other Chinese hillstream loaches, primarily those from Taiwan.

Cool stuff. While searching on google I found a 2003 thread on petfrd.com. Someone thought they had this sp.

Shari.....note subtle name change.

We had H. formosanum in the old Index.

It is correct as H. formosanus.

We need some better pics of this fish. Hopefully we can get some later.
Did that petfrd thread have any pics?

Yes, I don't like these preserved specimen pics at all. ;-/
Fixed the index name, but won't get to updates till tomorrow sometime. Thanks for heading that one off at the pass.

It had pics, but not of that species. Just the usual suspects.
