a lot of great advice here. Beani are found in northern Mexico and haitiensis in Haiti, meaning a big difference in temperature. Keeping the tank highly oxygenated for haitiensis works great because warmer water temperatures decrease oxygen levels. Where as beani need cooler temperatures leaving more oxygen in water. It's not gonna hurt anything to increase oxygen levels, but I doubt that it's a deciding factor with beani. Good luck with your beani!!!
