How to pair your Betta macrostoma! Mirror training wild types has some real science behind it. I will admit its fun to see a adult wild display, charge up and just look mean. But it plays a important role in pair bonding adults prior to breeding. Lets say you have a pair that's not feeling the love! Give them a common enemy like their own reflection to drive off and they bond and chase those trouble makers away. Mirror training should be done in moderation. You do not want to stress the pair out with hours of battle. I usually give the fish a few minutes a day and then I remove the mirror and let them be. It can take a week or more to bond a pair so take your time. Tank size is key also for success. I prefer 20 gallon longs for breeding wilds from the unimac complex. The combo of length and width will give a submissive Betta the space to run and hide. Good luck pairing and breeding these wonderful fish.
