My JD has a fungal infection (I am assuming as it is cottony growths). I have spent a lot of money on medicines and she is mostly better (I think) but she seems to be stuck in the condition she is. It has been a week with no improvement. I am to the point where I can't keep spending money on medication. She is in a 10 gallon tank on her own and I could really use the tank for 2 fish I just got that are very small and are bullied by the larger fish. I have wanted the 3 new fish for a long time and really don't want them to be eaten. My question is, if I put the JD in the main tank, will the disease spread to the other fish? The others aren't injured or stressed. I really want to let my little guys grow about an inch before putting them back in the tank, that way they can stick up for themselves. And if I can swap, should I thouroughly clean out the 10 gallon tank and filter and get a new sponge for the filter as they may be contaminated by the sick fish? I am in a predicament here and would love a way out! another option is a divider that will hold back 1" fish. thanks.
