Honestly, breeding Bettas is a bad idea to get someone into the hobby. SO many things can go wrong. Raising Betta fry is time consuming, space consuming, and would not be good fore a beginner.
To answer your question, YES, the fry do need special care. Lots of space, lots of water changes, lots of space for the fish when they mature, and you should cull as well.
