What is this little beastie?

Spotted this yesterday, it's very small. There is a chameleon shrimp in one photo, and the edge of a feeding dish in a few photos for scale.

Looks very similar to a lice, sometimes get them when fishing, but thought they were only in salty water.

Its an aquatic Isopod of some description.

I've never seen one like that. But have seen some marine isopods.

Most marine isopods are predatory.

 

Get it out asap.

Oops forgot to mention, most (but not all) freshwater isopods are harmless to shrimp as they eat leaves and other organic matter. However some are parasitic on shrimp. Might be best to remove it just to be certain.

Its not an isopod.  It is a beatle larvae from the family Psephenidae

 

also called "water pennies"

Completely harmless to your shrimp... and a rather cool addition to the tank.

You'll generally find them in flowing water in shallow streams stuck to rocks where they graze algae.  If it completes its life cycle the adult beetle will leave the tank  (and no doubt become a little dried husk on the window sill!).

I think @Grubs is probably right. The bug in the OP pics has 11 segments. Colouration is not a good indicator as the bug in the link has probably been stored in alcohol, hence its degraded colours.

I was not aware of these 'water pennies' when I suggested it might be an isopod.

Thank you so much @Grubs  It really did look like the thing in the link.

I think it may have come in on a rock that I collected from a strongly flowing stream which seems to be their preferred habitat.

I'll just ignore it if I see it again.

 

PS how do I make the "@insert name" link work?

      Great shot of Big Mama!  I reckon, 1 week tops for hatching.

      Great photo and news. The eggs are fading yellow but there are eyes so all looking good and there are a lot of eggs! Probably about half way ready to hatch.

      Let's hope the big mama can lay safely those eggs

      Sorry, I'm not in that area. 🙃   I prefer Glass tanks. Acrylic scratches way too easily. Often while cleaning algae off the sides. And once it's built up enough scratches, viewing gets obstructed.    Often going with LARGE tanks, you start to fall into custom built stands. So don't be surprised if you cannot find anything suitable.

      The easiest way wouod be to go to an aquarium shop and get a tank with a cabinet made for that tank, as that should be able to support the weight, as water in any large quantity is very heavy. I suspect it would have to be a glass aquarium at that capacity, otherwise the plastic would have to be very thick. It is possible to use a non aquarium specific piece of furniture but as you say it is quite risky, though I did help a friend do that by strengthening a nice decorative piece of furniture they had that they wanted to put a 350L tank on. It has been doing the job for 10 years but also bear in mind water marks, and we had to varnish many coats to make sure water doesn't soak into the wood etc. Its not really worth it in reality, it cost a lot of money to buy all the wood/stuff to strengthen it so was probably no cheaper, and a lot of time doing it. It may be dearer to get a combo tank and stand but much much easier and safer, and only you can know what ones you llike the appearance of? I would start off going to local stores and seeing if they have any you like, and even if not it will give you ideas?
