Tankmates with 4" polypterus endlichery

[Jyyx03]

My poly endli is in my 75 gallon grow out tank woth 2 paroons and 1 walking cat with 1 pictus cat i am thinking of getting more tankmates for the tank any suggestions

Those 2 paroon sharks will quickly grow and will start eating your fish. I had a 24" paroon shark swallowed a 18" iridecent shark. Tried to ate my 21" PBB too but manage to save the bichir as I caught it on the act. Turn the paroon shark into fish fillet and feed it to my other fish. That walking catfish will grow fast as well and become aggressive tank mates and also with food.
