I really like the zebra moray but i think my tank would be too small for him
(3-5 ft)
Apparently he doesn't bug fish too much, and i'd love to feed it the big meaty stuff it needs like squid and fish flesh.
But it looks as if the green wolf eel sounds like the best bet for me. It only gets 18 inches long so i'm assuming that's a smaller mouth, so it'd eat smaller fish?
Sorry if i sound really off. These are just my slightly educated guesses.
