Sounds like you took my advice to save the money and skip on the CO2 system for now. Good call.
The plant your describing "mini anubias" is "anubias nana petite" but in a 10 gallon tank you may be better off with an anubias nana (not the petite kind) they're a bit bigger.
The choice is yours, but if you've got the room, why not?
Java moss is a hardy plant, but it's not easily tied down. Expect it to go wherever it wants, but it's a great plant for beginners.
Java fern is also very hardy. It grows as slowly as anubias do. So don't expect it to change much.
Mickey looks very happy. I hope you enjoy making him a fun new home.
