So I recently bought a Delhezi Bichir thatās like 4 inches big. I want to put him in my 125 with my Oscarās and senegals. But since heās small and my Oscarās are like 7-8 inches I need to grow him out. I currently have him in a 20 gal high, but how long can I keep him in there before I need to take him out ?
