Were it not for the fact that I fear that it would also de-fish, de-urchinize and de-snail my tank, I'd be asking one of you mantis owners to rent me a mantis to de-crab my cube tank (well.. maybe not the über-rare 15 million dollar mantis mind you, but one of the others maybe..). (Worst infestation I've ever seen in a tank
At 30" deep with no rock moving option thanks to a 24" anemone, it's impossible to manually remove them. And traps only seem to catch my cleaner shrimp
) ... Oh well.
Neat that you have such a rare one.. who'dda thunk it .. usually all the rare stuff ends up in the U.S. or Vancouver...
