If it's in a completely sealed container? *Edit* Like in a canister that's been switched off. No, it will be almost all dead in a few hours. If it's not sealed, say sitting inside the tank then it should be fine.
My ceramic media bags are in totes with the fish, all submerged. These were removed from the hobs. However, I haven't checked the bio-bale in the corner filters. I'll have to open them up to see if its still wet inside...they're sitting in the tank.
Waiting on some final information about the new stand before I order.
In other small news, my BP Patch (avatar) is huge...she's so loaded with eggs her belly nearly drags the bottom when she swims low. I swear she must be the happiest parrot on earth. She puts out a farm of eggs every 2 weeks!
