ID needed "shrimp" found in pond

I was hoping someone could help me ID these. At first i thought it was some kind of Dragonfly nymph but its not. It seems to be a filter feeder similar to brine shrimp although some of these were up to 1.5cm long with red tips on the tail. I found them in a shallow muddy pan (about 40cm at its deepest) in a Game reserve near Kruger Park. They were plentiful. I found some daphnia and other organisms as well. Since i have no idea whether this is a fresh water crustacean or not, i was hoping someone might know more about it. I have posted some pics.

 

Would that not be Damsel Fly Larvae?

I am not sure but i doubt it. If you look at the first picture, the one in the back have at least 8 to 10 limbs which are contimually moving as if filter feeding. The one in the second photo on the net is some sort of Damsel Fly / Dragon Fly nymph but those encircled in red ... does not seem like it to me. But im no expert. And unfortunately the photos aren't very clear

 

Yes, I see what you mean with the multiple limbs.

They do look tasty though :eating:

 

I think they might be a FW copepod of some sort? i'm much more interested in the fw clam in pic no2

 

I can't help with the id I'm afraid, am just intrigued... in the centre of the 2nd pic - is that a tiny clam? was it alive?
Edit: snap @Henk Hugo! simultaneous posting!

 

Think we are gonna have to wait for @BugMan to come back from holliday - but they are definately from the Crustacean family

 

Fairy Shrimp!

 

Yes the clam was alive, for some reason i didnt know whether it was uncommon or not, as i recall ive seen a few there over the years. By the way what is the situation in SA with Freshwater Clams / mussels etc? are they rare? i can believe that pollution might be threatening them?

I am going to try and upload a video of the "shrimps"

 

I had a dog and his name was...



Eubranchipus grubii - Fairy Shrimp

Spot on @TankMaster

 

Here it is

 

They do look like fairy shrimp.

 

Ah thank you so much TankMaster! That must be it

 

No sweat! They make good feeders! Good find.

 

Thank you once again TankMaster. It sounds as though you had some experience with these. Would you mind telling me a bit more?

Found some more information on them:

@Zoom, @Marco, @Rory, @Zebra Pleco - gents these are not illegal. They are not really shrimps. Just got a common name with shrimp in it. You can buy the eggs at most hobby shops.

 

In that case... moved back to main forum

 

Yay...so we have one dude with fairy shrimp....

How are you keeping them alive?

 

@TankMaster Experilab used to sell their eggs for next to nothing. I believe it is possible to keep a breeding population.
