Forgive me if I'm wrong, but looks like there is no filtration on the tanks, how often do you water change for the betta's? Might like to give these a go.
yes.. they are fairly easy to maintain especially that they are right in the kitchen.. i put each one back in their cups they came in ..while i rinse and clean their tank.. then they all go back in the same divided area.. they are actually getting trained now.. lol.. And they do breathe air.. so it is not like they have to take in the same water that they poop in.. they are living a healthy life so far.. i only lost one Betta in the 4 years i have been keeping them.. get one !
