The nem that turned inside out was an LTA; he died within 24 hours. I'm still not sure what happened to him, but I suspect Marlin "loved" him to death. The BTA seems much more tolerant of Marlin's very physical attention. This nem seems helathy - for now. Since he used to eat much more frequently, I'm not sure how long he'll stay healthy. I'm trying to figure out if this is normal behavior during spawning, if he's losing his appetite for some other reason, and if Marlin plays any role in this situation.
