Medication and Single Quarantine Tank?

[Lija]

I'm a bit confused... What are you treating they from?

But yes, you can feed then while treating, in fact you should feed them! And supplement food too. They will need all nutrients they can get to fight with whatever is happening.

and yes you should keep them separately for the duration of treatment and follow proper qt procedures. Once fecals are clean after the treatment you can move them to their permanent home. Keeping separately is needed so you can monitor each separately and test each separately too. It is possible they are not going to respond to treatment the same and one or more will need follow up treatment.
