Hi Greg and welcome to discus .
Your discus have good colours and round shape . They still got some growing up to do and they look very promising already . Your angels look great too.
How long do you have the discus ? How did the mixing with the angels and rams went through ?
Did you Quarantined them first ?
I would put prefilrlter sponges on your canister intakes to prevent food and debris build up in the filter materials .
It would be nice if you can add some additional info. about the tank size , filtration , planned waterchange regime etc. You can also open a thread about your tank in "our tank journal" subforum and fill the tank questionnaire there for full info on your tank and fish . its easier that way for members to give you better advices about your keeping practices.
Good luck with your first discus and I hope that they will grow on you in time .
