When to move juvies to show tank

[Spawnstar]

How big should juvies be before moving them to a show tank (from 55g to 125g)?

At that point how do you adjust your feeding/water change schedule? Can you go down to twice a week water changes and once a day feedings?

I would say about 4-5". If your goal is not to try and grow monster size discus than moving them after they have reach 4-5" would be best. They will still grow in your show tank to maybe reach 5.5-6.5" if water condition is keep good.

If you still want to grow them,depending on the size of the tank,I would still try for atleast every other day.Feeding once a day while they are still growing will slow it down.Depends on what you want.
