No point feeding the main tank if everyone is in the hospital!
In your main tank, (the 90 I mean), there won't be any significant hosts for parasites to complete their cycle, so just maintain the SG, temp, and circulation. Put a few pieces of PVC in the QT for hiding spaces. If aggression gets to be too much, get another QT tank going.
