the first shrimp looks cute! :P

Can you describe the biotope in which you found wood shrimps?

**kuching** · 7th Jul 2004, 16:46

ok....wood shrimp always hide under the rock of fast flowing,clear water mountain stream....the water is not so deep...less than 1 meter.When i was camping in the mountain with my friends....20 years ago,i found the 1st "walking" shrimp....later i found its wood shrimp!It likes to walk...very fast when u put it on the land.

Hi Mike,

Nice pictures. Thanks for sharing.

The second and third picture may be the same type of shrimp. Over here, we call it wood shrimp or mountain shrimp. Sometimes also known as Singapore shrimp overseas.

The bit about walking on land is interesting. I do find that they sometimes try to get of of the tank for a walk, often their last trip anywhere.

Cheers,

Hi benny...thanks for telling me that is called wood shrimp.(you told me this when you visited me last time).Before I met u...i have no idea what should I call it...that's why i called it "a walking shrimp...."Ok..i got the pix of the habitat of wood shrimp...
pink arrow indicate the area I found the shrimp.

As they are filter feeders, it's no surprise that they are found at areas with faster flowing water.

Here's an old picture of mine showing how they feed.

Cheers,

interesting!

I always have the idea that wood shrimp is native to Germany after reading an article saying a fellow found one in his pipe few storeys up a flat.

What is the behavior of the shrimp in such a fast flowing stream? In the aquarium, they are more or less lazing around, hooking to somewhere and hiding. Are they agile, moving here and there or you gotta dig into rocks and under the logs for them?

Was told Pulau Tioman got a lot, probably amongst the rocky crevice in those fast flowing streams. HH even ate a lot of them, apparently not too tasty

Teach u guys how to catch the wood shrimp:

Put your net in the down stream...then ask someone or urself to pick up the rocks in the up stream....they will "run away" when your r took away the rock...then lift up ur net...gotcha!A beautiful wood shrimp...or a hill stream catfish in ur net!!!What a fun field trip!

**kuching** · 9th Jul 2004, 08:43

hill stream catfish shares the same habitat as the wood shrimp...here's the pix of catfish i caught on the same location where i found wood shrimp:

Michael, the pictures of the shrimps and biotope are very interesting. Natural habitat is something we don't get to see often on our urbanized island.

I find the first shrimp unusual. Did you take closer pics of the hairy pincers or have you released it back into the river?

For anyone keeping the woodshrimps in their aquarium, these are not your usual active shrimps. They prefer to get a good grip, where the filter outlet is, open their 'satelite' filter-pincers and collect food. For their size, they're fish-friendly but not competitive for food like yamatos. Remember to cater to their needs (daphnia, BBS, etc) and they are not algae eaters.

**kuching** · 9th Jul 2004, 14:33

huh...wood shrimp isn't an algae eater?

the shrimp in pix 1 still in my tank...show u guys more pix tonight...when i get back home.I keep this shrimp cos i never seen it b4!

**kuching** · 9th Jul 2004, 18:44

here r the pix for the hairy pincers shrimp....

**hwchoy** · 9th Jul 2004, 22:38

Michael, pic 2 and 3 shows what we call Singapore or Wood shrimp Atyopsis moluccensis. It is a fan shrimp and hence cannot feed on algae (at least not the non-free floating type).

Pic 1 shows some other shrimp. It has an arm much larger than the Singapore shrimp. Is it also a fan shrimp?

**RonWill** · 9th Jul 2004, 23:49

Michael, the wood shrimp opens up it's 'satellite' to filter organisms carried in the current, which is why it hangs around the filter output (or any spot where the current flows). As far as I know, it isn't an algae eater but interesting to observe it's feeding habit (collect collect, squirt squirt into mouth

)

Your new pic of the 'hairy pincer' shrimp doesn't show it's pincers well. Does it operate like a regular* or modified pincer (as in filtering type)? Care to shoot more pics when it's eating?

* 'regular' like those found in crayfish, crabs, etc.

**kuching** · 10th Jul 2004, 07:56

ok...i'm trying to use digital zoom to show the hairy pincers...not very clear but i'll take another pix when it is eating something.It doesn't own any "fan"...so it is a normal shrimp.....& of course not an algae eater.
Here is the pix:

**hwchoy** · 10th Jul 2004, 13:16

don't use digital zoom, get to maximum optical zoom, take the highest resolution possible. if we need to see the details at least we can download the file instead of viewing on screen.

**hanleong** · 10th Jul 2004, 14:37

gorgeous little thing.. it is awesome!

btw is it difficult to bring them back to sg? any issues at the customs at the malaysia side?

**kuching** · 10th Jul 2004, 18:10

fyi,i'm local kuching guy.....so i never gone through the custom...nobody cares what i'm doing in the streams......but i won't over fishing....anyway,i'll keep on finding "new" fish & shrimp...& show it to every1....!Enjoy....

ok..i'll try to shoot a better close up pix...next time...

**subzero** · 11th Jul 2004, 17:08

Maybe you can take a better picture after he settle down in your tank? I would like to see how it look like when he's feeding on food. Very nice unique shrimp indeed
