I definitely planned on that soon just waiting on tank to cycle.More like a bernese mountain dog and a chihuahua trying to mate, can it happen genetically sure, but the physics of it are way off. Obv easier for fish but the maroons might not tolerate it long term. Again i dont think anyone will have a definitive answer like this wont work period. Just really riskier, I would remove the 3rd maroon in the situation though as they will probably start to murder it
