doesnt look like it. Thats another reason I wanted to get pics of Grim, to check him out.
Billy and Mandy go for the other fish all the time, in fact, Harold got nipped pretty bad yesterday and is in the 5g QT tank for a couple days (he's doing great). I figure Grim doesnt get messed with because he doesnt really move much. The crays just see him as a piece of scenery I guess. There have been times that I've watched the crays walk on top of Grim in the log to get passed him.
