I'm planning on purchasing one of the 4 following eels: garden eel 14" max, wolf eel 18" max, zebra eel 48" max, or a snowflake eel 2' max. The problem is i don't know which one is the most sutiable for a reef. I have a 65 gal aquarium and my smallest fish WILL be a Maroon Gold Stripe clown 6" full grown.
