Hi,
We were doing one of our weekly cleanouts of the protein skimmer and found an amphipod - pretty large, in the cup. We couldn't get a good picture of it, but one of the kids found this shot on the internet. It eactly matches the one we found. If there's one, I guess there are more? Are they good for the tank? Should we leave them alone? Where do they come from (hitch hikers?)? Any comments would be appreciated.
