Petrolisthes type of crustacean??

This porcelain crab or at times are referred too as squat lobsters, are very good at cleaning up algae and cyano have read that they feed on plankton, the anemone crabs I have five of, they do that, but I haven’t seen these do that as yet.

I have always added them to tanks with inverts and never had probs with them and I have seen them over cyano and after they were there it was gone, the same with hair algae, so that’s where I get that from.

I have some blue ones already in the invert tank and rarely see them, more so in the last hour before lights out in that tank.

Some amongst them must not just consume plankton and focus on the rubbish life forms and detritus we need cleaned up in the aquarium as I have seen the green, blue and now the red ones.

We find the more common colours in the thousands on low tide collecting trips and I don’t bother with less attractive ones I will just say, but my clown trigger likes them,lol.

This little female I think it is has just shed so she is looking very pretty and has just joined the group in the invert tank.

They only grow to around the size of your thumb nail and the ones I have kept before seem to have a long life span, well the last ones I had were still alive after 4 years when I sold the reef tank before just tubs for 5 years and now these two tanks.
If you know this exact ones Latin name, cool,cause I don’t!

I only know its most likely a Petrolisthes.
The crustacean expert I go to for help is on holidays, government worker, so I have to wait till they comeback in January.

This all his auto system sent me
Unfortunately no data searches for Molluscs or Crustaceans can be performed during this time
Oh well.

Never seen them in that colour - only the green / brown ones we see locally

That one is very cool.... nice coloration

Great stuff

I like the blue ones,but the few i have chucked in i didn't get pics of,i will next time,they are awsome elec blue.

They are amongst the ones that you mean,its just you have to watch as the move very fast and the better colourd ones move faster,well they seem to drop off the rocks quicker.

The pretty ones are always more timid,lol,not with humans
