Hello all, I think I need some help here. :(
Here's the story: a while ago (march maybe?)I decided that I wanted to start a sorority. I bought a ten gallon tank with lots of decorations (all artificial plants), a filter, and a lamp. My house is kept at a stifling 85 degrees and once that changes, they'll be getting a heater. Having received some bad advice, I bought three girls and put them in. They only wanted to kill each other, so I put them in individual tanks because at the time, I didn't really have the time or money to get more to balance out the sorority.
A little over a week ago, I bought two new girls and put all five into the ten gallon. My three who were all raised individually are all big, bright, and active. The other two are quite a bit smaller, but they were fairly active and were both eating. Last week I noticed that one of my two new girls, the little red one, was a little swollen, her belly had turned sort of gold-grey (no pine-coning), and she was spending a lot of time on the bottom of the tank. I pulled her out and put her into her own tank, where I realized she had little white flecks on her body and fins. Assuming Ich, I put her under a heat lamp, covered the bowl with a dark towel, and did full bowl changes daily. I also fasted her. Well actually, I had to go away for four days so I left my roommate in charge of her bowl changes. When I got back last night, the Ich was gone but she was lying on the bottom of her bowl only coming up for air. She was less swollen, but still discoloured. Today, I found her dead.
Now I'm concerned for the other new one, simply because she's smaller and less active than my original three. Today she seems to be spending a lot of time hiding. Should I take her out and try to raise her on her own until she's bigger or will moving her just cause more stress? I'm not sure what to do :(
The water is tap water treated with a de-chlorinator and Stress Zyme. Full tank changes once a week. I had the water tested before I started the original Sorority, and everything was good (though it was low bacteria because of the 100% changes, hence the Stress Zyme addition), but I haven't had it tested since.
What am I doing wrong?? These aren't the first problems I've had with females :(
