Quarantine Tank Size

If I am buying 4-5 pcs 4-5" inches Discus. What should be the size of QT? Can I use 20 gals on it? Thanks

You can get away with it if you change about 80% of the water daily.

I’m now at 4 at the 4” size in a 45g. I would say the smallest would be a 30g and changing 20g daily.

Thank you!

I would definitely prefer a 40g breeder for this. Once water quality goes bad in a small tank, it doesn't take a long time for things to start going south really quick. The extra water gives you extra buffer room.

This is what I use as well..

With water change the 20 gallons will work for 4 to 5 of that size.

Exactly, I use a 55 gal and normally buy at least 6 around the 3 inch size at a time.
