ID of critter?? not seen in tank before

Morning.. well it is here in the UK and we've woken up to snow!!

We noticed a new hitchiker yesterday...

Just wondered if anyone could ID it for us....

Firstly no picture...

Reason: Had just fed the two clowns we have, and basically staring at the tank as you do... My husband noticed this white thing come flying out of the rock extremely fast!! very erratic as well, only about 1 to 2 cm in length, white or clear with brown bits on it.. moved so fast in and out of the rock, the clowns were fascinated by it and when it stopped they would investigate which would send it off again...

Anyway it landed at the front of our rock where we had a better look and the only way to describe it was whiteish looked a bit like a wood louse?? once on rock walked quite quickly too......

Anyway it flew off again and right into the filter inlet :huh: not to be seen again...... hence no picture...

I guess if there is one there is probably more ?

Anyone any ideas at all?

Thanks a lot

Hi..

yeah just don't know where to start to ID it....

is it a shrimp? I have no idea....

I think it was probably more like 1cm in length, not mm.....

Hi..

Well I caught a smaller one this morning.. seem to come out when feeding fish.. tried taking a picture but camera not good enough to focus on it

it definately looks like a wood louse two black eyes at the front.

Not amphipod I don't think, we have them running over the rock.. might have I.D'd it as an Isopod???

saved it for my husband to take a look at later...

but read isopods not a good thing to have????
