Jon, for once Kerry is completely right. It is catching the bast@ard that is the problem. I have tried everything and nothing works. Chris has offered to help me tear down the tank and take all the rock out over a weekend. I am not sure this would work because he hides in small holes . Once I was aquascaping (drinking beer) and I had a rock in my hand, WHACK the crack of the mantis claw on my finger. I dropped the rock very quickly and expected to look down at a very damaged finger. Amazingly there was no blood and and barely a scratch (lucky I guess). He is a weird creature, certain snails and crabs are gone within days of putting them in my tank. Some he never touches. I cant figure out the reason or the difference.
I have wanted a harlequin shrimp from the first time I laid eyes on one. I always assumed that would be a $20 piece of food. Last weekend I bit the bullet and bought one. He is still around today thank goodness! It is weird, I talked to Richard about it and thought maybe I would give it a try. He has never bothered a peppermint, cleaner, or blood shrimp. Richard said maybe he just like snails and crabs.
Yes there is a bounty on his head but I do not want to take all the rock out. We have a nice relationship going, he sticks his head out every morning and waves as I leave for work!
