Yeah - would have definitely been interested but should have let you know - my bad. I tried some a while back when Christian organized a group buy and used those in my overflows where I had a problem. Cleared out one of them but the other didn't - probably had to do with how many survived and for how long (they were a little beat up by the time I got them home and released them). Fixed that problem by covering the overflows but still have a couple of survivors in the main tank that irritate me no end.
