So it's been a week since my water parameters have gotten to no ammonia and no nitrites.. nitrates settled down to a healthy range. I picked up some fish after my water change. Not sure if it's because of the prime but my levels were still good tonight when I tested. I got some new guppies but found a female at the bottom and although she was a alive, her tail was chewed almost off. I isolated her in a breeder box but don't know if she has any chance of surviving. My male Dalmatian Molly has gotten aggressive with the additions. The other guppies are fine and swimming around. I think when I get my new tank in February i will dedicated it to only guppies.
