Discus in Juwel rio 180

[plod]

I am contemplating shutting down my saltwater tank, and going back to discus.

There is a lot of conflicting advice on the web with regards to keeping discus in a Juwel Rio 180 aquarium (101L x 42d x 50H)

How many could this tank hold?

Filtration would be via a fluval 307 external

i started with Discus in a Juwel Rio 180 about 5 years ago and found that 4 is pushing the limit in it imho. And did not really get even grow out rate with 4.

Have all my big adults now in a Rio 450 and use the 180 to grow out juveniles max 2 a at time for the eventual move to the 450.

Assuming your tank measurements are in cm your tank holds 56 gallons. Generally it is recommended one adult discus per 10 gallons.
