Glad to hear you decided to go with Endlers, they are great little fish. And your set-up sounds awesome for them. 
One thing I can think of though, is don't let them breed with Guppies. If they are in the same tank, they will gladly breed, and it's not a good idea to have Endler/Guppy hybrids running around, as most people want to keep the strain pure. Also, make sure you really are getting Endler females, not Guppy females.
