How large for green wolves?

[reef_research]

What is an appropriate size tank for two wolf eels with intents to breed and no other fish?

Thank you.

i believe they get around 18". I personally have one that is 12" long. I have a 65 gallon tank and it seems quite happy. Do have a lot of hiding places though.. so plenty of live rock for it to hide in.
