What would you attribute to these fish being willing to coexist... with anything else? Good luck with individual personalities? Barbiturates in their kibble? Were they raised together from little? A talent with tall-tales & photoshop? I notice you've got no structure so habitat enrichment isn't the key. I'd love an Aba but can't justify 1000Gallons for one fish.
No they were not raise as little as aba aba was introduced at 18" and lungfish at 9". If this is photoshop this is the best ever photoshoped that was done in the world. Even professional photo editor got nothing to say. Lol!
JDM for the win!!
