Hi everyone, I have my bettas in divided cubicals, well my males at least, and since recently i have blocked their view of each other for stress reasons. I have noticed they are now bored, laying about in plants or on the gravel, digging in the gravel, swimming fast up and down and doing laps of the heater or staring at the wall. I noticed at the pet store they sell little betta exercise mirrors, but i don't want a mirror in each cube all the time, that will just cause stress i think. My question is, to stimulate my bettas should i pull out the blocking divider for 10 minutes a day or every other day so they can have some form of exercise? Is it necessary for them at all?
