I've meandered through the stickies here, but all the information starts jumbling together, especially with my research done before I came here, so I turn to you guys to guide me towards the light.
I have two Veiltail bettas (didn't want anything too expensive for my first breeding venture). The boy is a dark reddish color with what seems green or blue hues to his fins. Very pretty to me. The girl is white with red fins. I have them in a 10gal with a divider between them. A very small filter is on the tank. Currently I don't have a heater (buying one tomorrow), but I siphon water out and add warmer water twice a day in attempts to keep it in their preferred range. Each fish has a little home to hide in if desired and I have a plant growing in each side. I currently have gravel in the bottom, but am considering taking it out (I heard betta's don't need/like it?). I feed them betta food and blood worms routinely.
Anyways, the girl is full of eggs. Her belly or what-have-you is bloated and I can see the white dot where her ovipositer is, but no vertical bars yet (not sure if it's due to her coloring or not). The male has built a rather nice bubble nest (it's torn a few times when I change water, but he always rebuilds, and it's getting taller/thicker!) and tends to follow the girl when she's near the divider, flaring and showing off. Sometimes she flares back.
I've put her in his side of the tank twice already. The first time, they both seemed confused as heck as to why they were together. He chased her, but she eventually holed up in the top corner of the tank and just.....sat there. He'd sit under his nest, swim over sometimes, flare, and then go back. A few times he'd swim over and she'd flare and he'd swim away before doing anything. The second time I put them together, he chased her a lot more, and it was more aggressive. Eventually, though, she holed up in her top corner again and the same thing repeated.
Are they simply not interested in one another? Am I doing something wrong?
