Yes, the pearl male did not take him too wall so at the first nip I tapped the glass and removed betta. If it was just female pearls I probably would have been fine. the betta just sat in the middle of my three and seemed fine.
I just added him to the black skirt tetra tank. the tetras looked him over and then got back to doing nothing. SO.. I hope he will be fine there.
he seems happy in between the filters current. He is currently watching the co2 reactor blow bubbles around.
Fish may seem fine at first for a while and then become unhappy with each other, its because for at least the first couple of days there will be no established pecking between the newcomer and the current inhabitants of the tank, but once the pecking order establishes itself, things can turn out for the worse. What other fish do you have in the tetra tank?
To be honest, he will be safest and happiest in a place on his own- a large bucket may not look great, but as long as its at least 10litres then it will make a fine and safe temporary accomodation for the betta
