Hey I caught this guy in the same stream I caught these fish in.

Anyone have any idea what this is. I didn't even know they were in the stream.

Am I going to be able to keep this? I have him in quarantine right now to see if he will live.

Thanks felljas....

Lamprey - AWESOME CATCH!!!!!!
 
Watch your fingers lol. Lamprey have a nice set of teeth on em.

Anybody keep them?

I would love to try...
 
No but I do know that they are one of the two jawless fish and they probably need to fed in a special way.

Chad
 
yeah feeders! LOL :D
i would love a pair
 
Well I HIGHLY doubt they are fast enough to catch feeders and they usually feed on the dead carcasses of other fish...

Chad
 
that was kind of a joke :)
i guess you'd just feed them 'real' meat, beef heart, shrimp, fish filets, squid and such
 
Lampreys don't really make good aquarium inhabitants.

Some species don't even feed as adults, the ones that do are parasitic, so they suck the blood and consume the flesh of live fish for a certain amount of time until they start fasting in preparation to spawn. Once they spawn they die.

Here's an article from NANFA:
http://www.nanfa.org/captivecare/lampreys.shtml

The bottom paragraph talks about feeding.
If you wish to keep adult parasitic lampreys during their feeding period, then be prepared to feed them living, freshly dead, or thawed frozen fish. However, one aquarium publication reports that the Ohio Lamprey (Ichthyomyzon bdellium) usually accepts chunks of spinach and chopped beef heart. When it comes to fish, lampreys are not finicky, but one aquarium experiment with Silver Lamprey (I. unicuspis) showed they would rather just hang on carp and black crappie than eat them. In that same experiment the lampreys did 81.5% of their feeding at night. Captive Sea Lamprey, however, are more active during the day. Eventually, healthy parasitic lampreys will give in to their natural urges and start to fast in preparation for a spring spawning. Becker (Fishes of Wisconsin, 1983) reports that Silver Lamprey can fast up to six months in aquaria, during which they decrease 4-22% in length and 52-57% in weight.

We had one in a 29g for awhile, my roomate brought it home because he too thought it was an eel. They don't really do anything....they just kind of sit there, slither around periodically and sometimes stick to the glass (which I didn't even know they can do).
All in all, pretty boring.
 
Shadow - interesting info! How long did it live? Did it live? What did you feed it? Did it eat? How big was it?
