Man.... Iwas reading the thread pulling for ya. Very sorry. It's real hard to grow them that big. I have lost my share of them. Every time I moved a sick or injured armatus out of the big tank to a smaller tank they died. Never again, will seperate with egg crate divider. I had a ray mouth one of mine into a weaken state eventually resulting in death. It's wierd how armauts can be so resilent one minute and dead the next. Good luck with your remaining armatus - true monster!
