They think so, but I'm pretty sure they're both female. They lay eggs every chance they get but nothing. Funniest thing is that they swap roles each time. One will guard the eggs while the other defends the perimeter. Next attempted spawn, they switch. I think it depends on who lays the eggs.
Nonetheless, they are very showy fish with boisterous personalities. I remember, when I bought them, Jeff telling me about how his wild pair would splash water on him every time he fed them. The same is true with these two, every time. I'll leave the room and hear 'pop, splash', 'pop, splash' and know to bring a mop when I return.
If anyone has a large male, let me know!
