Get new Discus

[Lewjo11]

So I have a 90gal tank with 6 fish 4 are 3.5-4 inch. And 2 are 2 inch or less stunted! I want 2 more cause 2 died before I didn't quarantine them. So I plan to use my 10 gallon hospital tank. How do you do it? Last time it took 2 weeks for the fish to show signs and the one that got them sick showed no signs! Just didn't eat! I just got him out of the hospital tank!

Thanks

I think there is a sticky for qt but I believe recommendation is 6 weeks?

I would get a larger quarantine tank. 10 gallons is too small, even for fairly small discus.

10 gallon is small for 2 discus as Kyla said , but you can get away with it , if your discus are smaller than 4" and if you are diligent in daily maintenance and daily WCs.

The usual procedure is puting the new arrivals for minimum of 4 weeks in QT by themselves and testing them for a minimum of additional 2 weeks in QT tank , mixed together with one of your old discus from your main tank .
If 2-3 weeks after mixing them everything goes well , you can transfer them all together in the main tank .

Years ago I tried to keep 3 very small discus in a 10gal qt, but even with daily 100% wc I could not keep the water parameters stable.
