nice to see a new discus fan ask. this very trying as celticfish has put in really valuable info up. great advice. [i have been thru all you said, why never read this sooner!!!!]
first ask yourself what is your objective...
do you have intention to breed? even if you don't, they will pair up when have 6. trust me. unless you got 6 males or 6 females or all playing hard to get
the pair will be territorial and peck the rest for space. in which case you should remove the pair into a bare tank and let them mate in peace. a ton of info available if you intend to breed...just ask
if you have planted tank it makes it even harder to breed. not advisable because of tons of factors as the expert breeders will tell you. from eggs eaten by the worker fish[sae, mini puffer etc] or fries getting sucked by the pump, getting lost can't find parents .... da da da.

maybe info overload.
well i've attached a pix of stunted with normal discus. it can be seen thru proportion of eyes to body. the lss is only a month older than the red white but much bigger.
the stunted red white is healthy but will never reach it's true potential size.
btw, this is old pix and red white

at a tiny 2.5 in.
so the defining look is the big eyes to body ratio. hope that was helpful.
