They are challenging for sure, but well worth the effort. Here is a summary of sorts on my discus husbandry for growing out juvi's:
55gal or larger for a grow-out tank
Dicus need to be kept in groups of 6 or more.
PH- the best ph is a STABLE one.
Feed 4-6 times daily, meaty foods bloodworms/shrimp/omega one flake (do not overfeed)
BB- the best way to keep up with the mess
Daily WC- a 25-35% daily clean up *actually easier than it sounds when you see the mess 6 young discus can make!
Auqaclear
HOB filters with a pre-filter sponge, no carbon, rinse prefilter daily
