My 125 started leaking so I had to move my fish to a 75. I had a male and female hartwegi among the group. All was fine at 7am yesterday but by noon the male had beat up the female. I put her in her own tank with some melafix and salt but she died a few hours later. I never thought they would fight like that. I figured the stress of moving to the new tank would have kept things calm until I could get home and set up more tanks.
You're not having a lot of luck lately, huh?
