In the tonga rock, seen a red thing in one of the holes after its been in the tank for a week, just now seen it.

We figured it was a crab by the looks of it, so we took the rock out, but couldn't get it out.

Its red, not hairy that I can see, but has very large claws for its size, and the tip of the claw I could see is black from about half of the pincher to the tip.

The crabs body is about inch to inch and a half long.

How does one normally trap a crab?

It's probably a gorilla crab....Look them up on RC. They're bad news. I had one hitchike on a nice mushroom rock I got from the LFS and I saw it, and left it alone. After a month or so, I looked over at the tank and one of my peppermint shrimp was getting eaten by it. I pulled the rock out but didn't want to do a fresh water dip, because I was worried about hurting the mushrooms, I finally filled a syringe up with isoproply rubbing alcholol and squirted it in the hole. Dead crab. Managed to pick it out with some forceps, and rinsed the rock off very well with tank water, then put it back.

Tom has a great picture of how big the things can get. I'm sure he'll post it. :lol:

Well I had a dream last night, that I took the rock back out of the tank, and the bugger just fell out into my hand, but it was only half a shell and one big claw and his insides, no legs.

Well go to the store get a shrimp to put in a bottle to trap the crab, come home, and had a strange feeling since I couldn't see him, but looked in the bucket of freshwater that we had dipped the rock in, and what can I see in there, but the claw, so look closer, and see that it was him, but only half of him with no legs and just the one claw.

I think I must have seen it without realizing it, and while I slept it peiced it together. So I no longer have him in my tank. Of course now I think he might have been helping the ammonia spike I have been experiencing.

What percentage of a water change does one normally do in a normal routine water change?
