[Delphinus]

I thought about Interceptor too Harvey. I don't have any, nor have I spoken to a vet yet, so hopefully it doesn't have to come to that -- although I am accepting it as inevitable that eventually I will have to one day source some and do some treatments. In this tank I also have a porcelain crab, three peppermint shrimp, some of the "masked" acro crabs, and theoretically an emerald crab (although I haven't seen it in a few weeks now) so I'd have to catch all those guys and put'em somewhere else for a bit, if it came to that.

I'm thinking that since I can usually find this fuzzy crab without too much effort (it's always on an acro... not always the same acro, seems to "acro hop") so I'm thinking as long as I'm quick on the draw I can pull the whole colony out of the tank to catch the crab, rather than try to chase it around with tweezers.

The acro it came in on is pretty much decimated. I thought it was STN but I was unable to determine a cause, but now I wonder if it's just that the crab had his fill, and is now moving onto the others in the tank.

The thing that really threw me with this guy is the eye colour. They are most definitely sky-blue. Had they been red, I would have known not to trust it from the get-go. I don't know enough about crabs to know if eye colour is really significant, i.e., can there be variability of eye colour within species or not -- I don't know. It's so hard to do a search on RC these days so I hadn't even bothered trying to delve into it further. Last night was the first inkling I've had in 3-4 months that maybe I've made a mistake in judgment in trusting the crab would be harmless.
