I've had my 29G community tank up now for three months. Started with 2 female mollies, added 8 neon tetra, and the highlight was purchasing four female hifin lyretail swords from a breeder. The swordtails had a difficult trip from the breeder, where quite nervous in the 10G quarrentine for two weeks. The male tried to jump out of the tank, hit the cover and damaged his swim blatter (died in 2 hours). They never ate as well as my other fish. When I brought the three females into the display tank, they did not compete for food. One was particularly poor at finding food and died of starvation (I was intentionally overfeeding at the time). The other two settled in after a couple weeks and are eating OK, but not nearly as much as the mollies. The mollies and the swordtails have always left each other alone. The mollies are agressive to each other, but the swordtails have never bothered each other. The mollies normally feed at the top, but will eat anywhere. The swordtails normally feed mid-to-bottom, staying out of the way of the tetra.
Recently I had a fungus outbreak that effected the mollies and one of the swordtails. I moved the three of them into a sparse hospital tank with a couple sponge filters and a couple plastic plants. Everything seemed to be going OK in the hospital tank, as all three where eating well and active. At the start of the third day, the swordtail decided she didn't like the mollies moving in on her food, and started attacking them. By the time I seperated them, the mollies where trying to hide behind the heater. Both have chunks missing from their dorsal fins and tails. Lucily, I had a tank divider on hand.
My questions are:
1) Should I add an antibiotic to the fungus treatment (using two different anti-fungal meds on the advice of the main fishkeeper at a LFS).
2) Is there anything I can do when reintroducing them back to the display tank to help keep the swordtail from attacking the mollies?
