I don't live in FL, but my understanding is that retics need a license due to the possibility of becoming invasive (just like burms).
You will need a license to sell if you are planning on breeding BPs anyway (FL has actually done "sting" operations trying to catch people just selling a pet off CL and similar services without permits). I can't remember what the permit is called though.
Hopefully, a FL member will see you post soon and be of more help.
