thanks guys. i will keep trying until i get some wrigglers and then i will move on to my next breeding project.
but to tell you the truth, i thought i was gonna lose all of my fish. one of the cannister outlet fell from the tank and drained half of the water before one of the fish knocked the inlet pipe up, otherwise at least 3/4 of the water would have been gone. they were swimming in only half the tank with no filters or air for how long, i didn't know ( i didn't go to the garage for more than 2 days). but 2 days after the water level back to normal, that's when all the action happened.
