I chose vinegar eels because they are tiny, carefree, and don't smell! I chose banana worms because they are tiny, mostly carefree, and don't smell too bad...forgot where I read it, but they said banana worms culture smell less than microworms, etc.
I got both cultures off aquabid...let me know if you want me to post sellers screen names...both of them were awesome, professional, with large cultures you could start feeding from immediately...a lot of people sell culture starters that you have to wait a while to use, so if you already have babies, you want a large culture to begin with!
