Has anyone who has a community tank with a male betta ever notice any corrispondence with their nesting and their aggression levels?
My situation is this, I have a 10 gal that I would like to turn into a community tank with one of my two boys. Beast, in his 2.5 planted tank, has never made a nest. Merlin, in the 10 gal half filled, makes some pretty awesome nests. I noticed this morning, after he had created a new nest, he seemed more protective of his territory, patroling the area with spread fins and even flaring at me. Both fish flare at their reflection but this is the first time Merlin flared at me or anything else.
I'm wondering if Beast might be the better candidate for the community tank since he doesn't seem to nest and might be less territorial. Or should Merlin be fine if I completely revamp the tank like I'm planning and add him back last?
(Another factor to the equation for those that don't know, Beast is at work and Merlin is at home and that's a 50 mile drive so switching them would be stessful on both boys. However, if Merlin is not a good choice for the community tank, it is an option.)
