“No I'm not saying that but I'm saying this isn't that serious, I posted this to have a conversation about eels in established reef tanks”
These threads are what turns into the dying eel and sick eel threads you talk about below; so it is serious.
As far as your question you claimed you wanted about an eel in a reef tank, yes Ive kept my eels in a reef tank. Two of them in my old 125 gallon that was a reef. Decided not to keep a reef in the 300 gallon, too many nutrients created by my eels and predatory fish I keep. But it wasnt an 18 gallon reef with an eel like here.
