hey yalli recently got my first bichir and it stays mainly to the surface and i do not know if thats normal cause it goes to the bottom for about a hour before going to the top and sitting around 2-3 inches below the water line and im worried it could be struggeling as it stays in one corner the tank is stocked with two giant raphael cats 1 synodontis and a bunch of adult bns and a crystal parrot fish is it normal as the bichir is around 4 inches long max and it is just on the surface and im worried about it
