The thing is this would be the first time he's hidden like this. He's always in this one place hanging upside down. He molted on Monday (for the 3rd time) and he looked kind of 'spent', if you will, and we thought it was just the trauma of the molt. Then on Tuesday, in his usual spot...he just didn't look right and again we thought it was b/c he was still trying to harden...he also ate his shell, fyi. Now, we also have a fire red shrimp but they have never faught or anything - the fire shrimp was in the tank first and they had their tiffs or rather, the fire shrimp had fits but the property line issues were established right away 2 months ago. Could the fire shrimp have eaten him?
