I know that many dwarf cichlids live in large groups. Only during spawning season do these groups break up into pairs.Yesterday, I caught and removed the tetras, and within 2 hours, I saw the most intense spawning displays out of the Cichlids since their failed attempt. Will change work?
Perhaps the cichlids misinterpreted the group of tetras and thought, "It's not spawning season, let's wait until the others start."
