Actually, the males do have one big claw. I wish I saw this earlier because I already purchased three females and one male. Since I have bought them they have found their way out of my tank on numerious occasions. They like to climb up plants and airline tubing and make their way out of the crack in the hood where my filter goes. Since I've had them I rarely see them on the bottom of the tank where I want them, and actually found one of them near my refridgerator in the next room. (I now can't find one of the females, hopefully she is alright).
But what makes a fishtank brackish? Is it the gH and kH of the water?
