Good choice to do bare bottom when starting out. Depending on the size of the discus you get, you maybe want a smaller grow out tank like the 29 gal. I suggest getting adult discus which don’t require as many feedings and daily water changes.

You need a heater and ideally more than 1 in case one fails. There are many others ways to
Set yourself up for success. Watch Al’s lecture on discus too. Also, buy quality discus and clean water are the IMO. 2 years into this journey I’m still learning a lot. .
