That’s true, and it’s so hard sexing Oscar’s lol. So far they both get along. It’s just the JD being an a** to my albino tiger rn. Which is why I’m planning on getting rid of him although I don’t want too. And I really like bichirs as well so I wanted to keep all 3 together but like for life till they die. Not as a grow out, so which is why I want to make the right decision.The only issue I can think of if the Oscar’s matured and paired off but that will take years because their juveniles.
