JJmoneyman....any luck getting them out other than manually doing it? I just counted 40+ of them and the shells are quite hard..Luckily my tank has never been really stocked..been running since December of 09 but the only livestock is two clownfish and a blue throat trigger. I have been lucky enough to also collect about 5 aiptasia, 200+ pineapple sponges, and about 20 limpets. Would really like the aiptasia and these guys to be gone lol...was thinking about a copperband butterfly? I feel like I might be the only one running a hitchiker majority population on the board
