I got three of these to keep worth my flowerhorn, it did not succeed so I moved them to 40 gallon, I think I have 2 males and one female, I like one male the most so I am giving up another male for now and mostly will give away female as well in future.
Tried one with my flowerhorn. He's sturdy enough to take the beating but it broke my heart to see him hiding constantly and I was worried he wasn't eating. He's much happier in his own tank with another little one. I can't imagine giving him up.
