    Most of us have found unwanted hitchhiker crabs and sumped then in case they nip coral, eat fish, etc.
    I threw a number in my sump about two years ago. Seeing as i havent cleaned my sump since then, who knows how big they are now.
    Out of interest does anyone have pics of what there sumped crabs look like after being left to their own devices for a few years?

    The one hitchhiker crab I had perished when we had a power outage in winter, the water in the tank was too cold (he was in a little pico and temperature dropped too quickly). He had grown quite sizeable though, almost the size of a R5 coin when he was alive and kicking.

    I scratched in my sump to see if i could find any crabs. Besides a ton of mussels and limpets, the most exciting thing i found was tons of this yellow sponge -

    @459b
    I wonder if they are hiding in your live rock? I had one in my 250 for over four years living that I did not know about because of how clever it was at hiding in the liverock :p

    Sounds cute :) Wish they didn't go after fish and inverts, would have been nice to keep them as part of the livestock.

    Most likely. I had a very quick look, will maybe unpack the sump and look properly this weekend.
