well, i decided to give it a go and the sen always kept to itself and the ornate never seemed to even look at it, but earlier today, i couldnt find the sen and the ornate was laying where i couldnt really see it. then a little bit ago, the ornate came out and has a nice, long lump in its stomach...oops. i just hope he doesnt have any problems w/ the sen in its stomach. i got it from petsmart and was very small, so i'm not so worried about losing it but it always sucks when you lose a fish thats not SUPPOSED to be a feeder.
