I was wondering if any one could help me with an aquarium problem? I have a 10 gal. set up for about a month, I bought 3 fish (2 mollies and 1 corry cat) after it had set for a day. One of the mollies was female and had babies to my surprize, well she died and the babies lasted a week, then the male mollie died for no aparent reason. I changed half the water and and bought 2 more sailfin mollies, male and female, the corry is doing fine. I also bought 2 balloon mollies. The balloon mollies died the next day, so I took them back and got 2 more, they both died the next day. The male sailfin had been chasing them relentlessly. Now the sailfin and the corry seam to be fine. I have changed half the water again today. The temp stays around 79 to 80 degrees. My question is.... why would the baloon mollies die and the others be fine? Is it just that those type of fish are to sensitive? I don't think I will buy any more of them. This is not the first tank I have had, I have had them since I was a young girl and just sold my 55 gal and went to the 10. I have always had at least a 29 and I have kept goldfish and tropicals most of my life but this has me stumped. Any ideas?
