How To Care For A Freshwater Eel?

Hi all
The other day I agreed to rescue the few remaining members of my friend's tropical tank. As far as I was aware there were just a few tetras so it wasn't going to be a problem. As I was chasing the fish around the tank just now, I overturned a clay pot and underneath it was a freshwater eel which she had apparently totally forgotten about. I took it because I didn't want it to be killed, but I have absolutely no idea how to care for it. She assures me it doesn't need any care as she has never fed it anything special but that doesn't sound right to me. It's probably about 3-4 inches long and all brown. It's obviously really tough and I really don't think it'll be a danger to any of my fish. Even my cories will be fine, won't they? I will be very grateful for any advice

That was my first thought too. If you decide to keep it, you need to be aware that they need a sand substrate as they like to burrow, and they need to be in groups. The reason it was hidden in your friend's tank (assuming it is a kuhli) is that it was alone. They come out more if there is a group of them.

You could always ask your local shops, one of them should take it, probably for free. Few shops actually give you anything in return.

There aren't freshwater eels as far as I am aware. Eels are either marine fish or they are catadromous. This is a posh term for fish that live in freshwater but must migrate to the ocean in order to breed. Caring for them is problematic. They are aggressive, predatory, pugnacious and generally can grow to lengths in excess of 1 meter. They can survive for extended periods out of water as long as they can remain damp. They are experts at escaping from tanks. They are quite willing to take a piece out of any stray fingers that come within range and are generally pretty ugly things too.

About the only positive thing I can think to say about them is that they are delicious!

Lol Thanks Steve As a vegan I can't say I've evr tried eel, but we've actually worked out that I was wrong anyway and it's not an eel at all. It's actually a kuhli loach!

Yeah, I know. I thought I would include some data about eels in case anyone else came to read the thread based upon it's title. Just for completeness sake! 

I called eels "pretty ugly" above. Moray eels are marine eels on steroids. They are very, very ugly ! Personally, I would never ever keep one of these brutes. But "horses for courses" as we say!

That's quite funny. I come from New Zealand and eels live in basically every large stream there. At primary school camp once, we were woken up in the middle of the night by the teachers who were looking for a bunch of dads and some students and it turned out they had all gone eel fishing! One of the dads came back carrying this eel which in my mind was as big as he was, but actually it must have been at least a meter long with these massive teeth. Knowing those were in the water meant that most of us girls refused to swim for the rest of the week.
