Neogastromyzon crassiobex profile*x

[Jim Powers]

*Work in progress*

Scientific Name: Neogastromyzon crassiobex (Tan, 2006)

Common name: None

Synonyms: None

Distribution: Borneo

Sexual Dimorphism: Unknown

Maximum size: 2 inches (5cm)

Similar to: Gastromyzon and other Neogastromyzon 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 would probably consist of bloodworms and brine shrimp as well as algae.

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

Temperature: 70ºF to 79ºF (21-26°C)

Breeding: Not bred in aquaria

Notes: This newly described species was formerly thought to be Neogastromyzon pauciradiatus and is not known in the pet trade at this time. N. crassiobex, as well as other Neogastromyzons might show up as a contaminant in shipments of Gastromyzon species found in the same waters.

Droooooooooool! Good job!

Martin.

[Jim Powers]

Thanks.
I just wish some of these neogastros would show up. Check those gastro shipments well!

[Martin Thoene]

I coded the article link and changed "newly discovered" to "newly described" because it was discovered before

Martin.

[Jim Powers]

Good idea. I thought about that as I was putting this together, but forgot it by the time I finished.

[Emma Turner]

Drool!!!!!

[Jim Powers]

There are some nice looking neogastromyzons. You can't really tell from this pic, but they have narrower bodies than gastros and their pectoral and pelvic fins don't overlap.

[Jim Powers]

By the way, I had wanted to add Hypergastromyzons to the species index, but can't find a pic of one other than the pickled variety.
If someone happens to run accross one, let me know.
They are intermediate between the gastros and neogastros...yet another cool hillstream I would like to find.
Imagine an all Borneo tank with gastros, neo and hypergastros, and orthos.... Talk about DROOL!!!

[Graeme Robson]

Superb!!

Do we retain the Neogastromyzon pauciradiatus entry, or does this one replace it?

[Jim Powers]

This replaces it. I can't find any pics of that species or any other neogastromyzon, for that matter.

Thanks Jim.
