If it has been exposed to air, then it won't survive anyways, so it's as good as gone. You probably have tons more in your tank -- they are pretty common.
It apparent that sponge was free loading and up to no good,by the fact that it was snooping around the tank.
LB had no way of know what that sponge was up to,so did what he (LB) had to,to protect his tank,home,and family.:D
I'm going to file an appeal. This has been a miscarriage of justice! You will end up paying for your crimes, Sir. Justice does not turn a blind eye to cold-blooded killers like you!
