Do I need to take some of her water out and add new? I added some tank start to her tank tonight.
We do not have a heater. We live in Tx and we have has some very cold days lately a heater might be what we need.
Thank you for any and all advice. My son loves Snowflake and is very sad she is not well.
Your issue sounds like it's the same thing. Water quality and temperature.
In an uncycled 5 gallon tank with a filter, you should make 2-3 50% water changes per week. Make sure the water you add is conditioned and is within a few degrees of the water already in the tank.
A heater will definitely help the temperature to remain constant in the 76-82 degree range and your fish will be much healthier.
For this first change, I'd change out 75% the first day, and 50% the next two days, then turn to a schedule of 2-3 50% changes per week.
