The strangest thing......i had a electric yellow and a gt and a red terror and a clown knife in my tank.....and i was looking in my tank cause i havent seen the knife out lately cause hes usually out when the feeders are gone looking for food....and hes gone....no where to be found.....i even looked under the cave and pots....hes just plain gone......and my gt and rt are to small to take out a big clown knife...and eat it before i would notice the fishes body? i just dont know
