Hey guys...I just purchase 2 young polypterus ornatipinnis about 4" in size....I just release them now and one of them is hanging out on the top of the tank and just resting on the spray bar while the other is on the bottom resting on some drifwood.....Is this natural behavior, i thought they like to stay mainly on the bottom of the tank.....And what should I feed him??? the guy in the LFS told me that they are eating sinking pellets, should I stay with the same diet????...thanks for the advice....
