Ok, so I'm about to get a 60 gallon tank for my bettas. I would house 5 in it. They would each have an equal amount of space. I heard from someone that when males constantly see each other it shortens their life span. Is this true? My priority is to make sure these fish are living the dream. Would opaque fiberglass work if I got holes drilled in it to keep them from seeing each other? I don't want them to stress out.
Second I want to know if the dividers would need to be siliconed in place or if suction cups would work? I'd feel absolutely terrible if I was away and they wiggled their way past the dividers because they broke the suction. I just want everything to be perfect...
Last but not least, would I be able to house males and females in they divided tank? I know that they release a "scent" that lets other bettas know they're there. Would the smell of the male bettas stress her out of cause her to become egg bound?
