That's ok
These things are great to have good conversation about.
Where you able to check out the links I had in the reply?

While you're planning (even though they are small) keep in mind they need space.
Some say 5 gallons/frog;
Subtracting the space substrate, plants, background etc. takes up........all begins to minimize actual space allotted to the frog.

You want to consider what area of the enclosure the frog will be spending most of its time in as well. In a group, the more they a have to share a small space will increase the day to day stress.

ie
an exo terra - 18x18x24 is about 33 1/2 gallons.
about 18x18x6 " is taken up w/ sustrate -- reducing usable space by about 8.5 gallons ---leaving you with 25 gallons

Food for thought !

Then there is the argument of same species different morphs. That's dangerous territory in PDF land. Highly frowned upon.
Interbreeding will muck-up the color morphs.
