Definitely. A non planted tank only needs about 6-8 hours of light a day. The more light, the worse the algae can be. Planted tanks need about 8-10 hours of light per day, and it can decrease algae, since the plants take up all of the nutrients from the algae. I've had a 10" female Red Oscar act the exact same way, and the light was a fancy one that had a built in timer and dimmer. The reflection thing, you can't really do anything about it since you use the room light. The only thing I can think of to prevent it, would be to put a blanket or towel over the tank before you shut off the lights. That way it can prevent the room light from causing reflections and getting him riled up. Having plenty of hiding places can also help, floating plants in particular. According to my LFS
, the males use floating plants as territory, and I've seen them build really good bubble nests with floating decor. You might also want to watch them pretty carefully, they can get a bit mean when defending the nest. I'm not sure if you need to remove the female after spawning like you do with a Betta though. I've got two males of my own in a planted 55g, with some floating decor.
