Hello again, I'm just wondering why making your betta flare (with a mirror) is considered playing with it. Doesn't flaring just stress them? Are there any benefits to it? Thanks in advance.
Watch him closely while he is flaring and you will see him poop, Also put a ping pong ball in the tank he might flare at it and push it around, Interact with your fish teach it tricks it all adds up to a better quality of life for your fish, and its fun for you.
