I have a male Breidohri and a Fenestratus of unknown gender. The male is digging a hole in front of a flowerpot, and picking at the inside of it, but mostly just spitting sand around. The female is just hanging around the flowerport. They won't let other fish near the 3rd of the tank with flowerpot in it. They team up on other fish now, too. This started very suddenly, 3 days ago, they totally ignored each other. So, is this about what goes on when fish spawn? How long are they gonna do this, because it's pretty annoying and if they do hatch some fry, they'll be hybrids. I've got the rest of the fish crowded up on the other side of the tank, and they're arguing all the time. If this is just a few days kinda thing, OK.....but if this goes on for weeks before they decide to lay, I'd rather separate them. Way too much trouble for hybrid fry.
