Hi guys,

Need some ID on this :alien:!

Found this rice sized larvae thing in my aquarium this morning!

I fished it out and took a pic, but its not that clear.

Anyone with ideas?

Must have come in the aquarium via new HC i bought.

Just to clarify with a little more info,

Head is on the left, with lots of legs either side, plus 2 antennae-like appendages coming out from its backside on the right of the photo.

Cant quite see it in this photo!

But here's a closer pic!

looks like it could be scuds (gammarus). perfectly harmless.

How many do you have? it can be used as a food source for fish or crayfish.

You can keep it together with your shrimps!

Well, it really depends on the species of amphipods.
Especially the amphipods of the genus Hyalella, for example Hyalella azteca, which is bred as fish food, are not good tank mates for shrimps at all.
Hyalella azteca is reproducing very fast and they eat the same food as shrimps do. So in a tank with Hyalella little shrimplets often starve and don't have a big chance to survive.
There are even reports that Hyalella azteca kill and eat little shrimplets after molting. Don't know if that's true, but it's a fact that Hyalella is at least a food competitor to the shrimps and that only few shrimplets survive the first days if there are lots of Hyalella in the tank.
And, last but not least, Hyalella azteca eat moss and some other kind of plants. Therefore at least this species is not recommended to be kept together with shrimps.

Btw. according to the photo I have another suggestion what it perhaps could be: A waterlouse, for example Asellus aquaticus or a similar species.
But unfortunately the photo is rather blurred, so it's hard to tell.
If it's Asellus aquaticus then they usually are no danger for the shrimps. Similar to amphipods they eat the same food as shrimps, but they don't reproduce as fast as Hyalella azteca.
