Im with quarryshark on that. Fish can last a long while without food. He looked pretty good when i got him. There was one problem at first. When i was acclimating him , he looked like he was running out of air. Breathing really fast and lying on his side. I know butterflies are a little tricky, but not that bad. I did everything with this one and he dident respond to anything. The only marks i can see now are , ragged fins , and looks like some hemoraging around his gils and upper part of his body. I treated the tank with greenex, it couldent hurt. But nothing. The guy at the LFS
, who i know pretty good, said he was eating brine shrimp. Oh well, i guess it was just bad luck. Nice fish though all the same.
