Gastromyzon unknown02 Profile*x
*Work in progress* AWAITING ANY FURTHER INPUT FROM HENDRA
Scientific Name: Gastromyzon unknown02
AKA Gastromyzon species SK02
Common name: Hillstream loach
Synonyms: None
Distribution: South Kalimantan, Indonesia
Sexual Dimorphism: Females probably plumper all over than males.
Maximum size: 2 inches (5 cm)
Similar to: Other Gastromyzon species.
Care: Inhabit fast flowing streams over sand, gravel and rocks. Aquarium must duplicate these conditions as fish have very high oxygen requirements.
See: Hillstream Loaches: Specialists at Life in the Fast Lane for more detailed explanation.
With all Gastromyzon 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 Microsoreum. These will grow on rockwork or driftwood.
Feeding: Good quality flake, sinking pellets, algae wafers, thawed frozen Bloodworm, Mysis Shrimp, blanched Spinach, Kale, natural algae an advantage.
Water parameters: pH:7.0-8.0 Hardness: Medium Max dh: 12
Temperature: 75.2ºF to 82ºF(24-27.7°C)
Breeding: Not bred in aquaria.
Notes: This fish was collected by Hendra Budianto in the wild and designated SK02 for reference purposes. It is notable in mature specimens for having a pronounced secondary rostrum (nose area) that overhangs the lower and is noticeably longer at the outside edges, giving a concave appearance when viewed from above.
The habitat was a hillstream about 8-12 M wide, up to about 80 cm deep.
The water was very clear and the current strong.
Temp. 26 C, pH 7.8, TDS 054 ppm.
Substrate of sand mixed with gravel and rocks.

Is the old entry in the index Gastromyzon sp.(2) equivalent to u02, or should we delete the sp. (2)?

Yes, they are all there. And I killed it...
The version that will be at the community (but don't worry, it won't look like this...) is HERE
It's sent.

Most excellent work!
(Martin removes welding mask) I must depart soon to the downtown core where my Dentist awaits to do evil things to my choppers. I will return (drooling ever so slightly) in due course.
Might get brave enough to attempt moving another profile ...or more.

Resistance is futile. You will be assimilated.
Did you notice the one entry in red? Wondering if it actually is a duplicate or if the second name is supposed to be Nemachilus...
