I just set up my 10 gallon tank and filter a few hours ago. The filter puts in a decent amount of bubbles an airrates the water well.
I know that Bettas need to breath air to survive a non-oxygenated envirement. Well, my tank is oxygenated very well. So, do you think a sorority could exist where the females don't need to breath? I'm pretty sure they still need to breath, but I'm not certain.
I'm just wondering. If they need to breath I might see them every once in a great while LOL. (I don't have a sorority yet, but I'm guessing the females will hide ALOT.
