Since I got a new betta, my first boy has been hiding under his sponge filter more. He will go flare at the new boy, then swim really fast to the other side of his tank, and then down under his filter. Before I got the new boy he had never flared even once. The new boy flares and then hides too. My first boy is still eating just fine, and comes out and ignores the new fish when I go up to the tank. I put up a divider for now, but don't want to keep it long term. Will they eventually get used to each other? If they will eventually get used to each other what is the best way to get them used to each other? Should I take the screen down permanently, or just give them some flare time a few hours a day?
Sorry for the horrible grammar in the title. That was an oopsie! I don't know how to change it!
