Discus

[lee]

Hello, Ive aquired a 50 gallon fish tank all ready for fish. Its heated and runs a fluval 404. I have my heart really set on 3 discus. I work at a petstore and next month c.b tourqoise blues are on sale for $30. I wanted the discus, a few cardinals and rummey nose and a few algae shrimps(love em) and a few flying foxes or cories. Ill ad them gradually and slowly. should i add Discus or tetras first???
Does this sound ok???? cause i know discus are somewhat finiky but i love them and know alot about them and will put in the time....
What kind of plants would do best as well?
Im a reptile guy but had my heart set on discus.....thx
