Help ID river fry

[zoom111]

Hey guys I have a small 8g cube on my nightstand, has been running for about 6-8 month.

If someone can help ID this fry caught in the river that would be great, thanks !!

(was thinking walleye but not sure)




Livestock includes

5 head/taillight tetras
2 pigmy cories
1 siamese algae eater
1 river fry

Trying to ID any type of fry is practically impossible, many fish tend to look similar at that stage.

thx for the input, thought maybe with the fins, body style, coloring and markings I could hone in on possibilities. Although pictures I provided aren't the best so it's tricky to tell.

In a month or two I'll probably be able to tell  But will definitely post and update incase anyone is curious !

Remember to be careful....

You could get in trouble. Transporting live fish is against the rules also keeping certain fish in captivity without permits will cause you problems.

Also NEVER put is back were you caught it as it could introduce disease to the river. Also the fry could cause problems for your tank. Could have parasites, carry a virus etc.

If Aquaviewer is still around he did a talk on this subject a couple years ago.

Good luck on it I'm also interested to see  what it is.

Agreed...once you take a fish from the wild and put it with non-wild fish, it is very irresponsible to put it back. You never know what your already captive fish may be carrying.  A disease that your fish may be immune to could wreak havoc on an ecosystem that does not have the built up immunity.   It's not right to do that to a natural ecosystem.  Hopefully you'll have somewhere to keep it long term, whatever it ends up being.

As far as your existing fish are concerned...be careful.  Diseases are one thing but parasites can be a royal PITA to get rid of, especially if they're the internal kind.

Wild fry are always hard to differentiate until they get bigger.  I'm curious as to what it is also. 

It looks skinny.  Is it eating in your tank?

Thx for the concern, I figure with a fishing licence you are able to fish and keep the fish, this is a similar scenario, but I simply kept my "catch" alive.

I will not be re-introducing him to the natural eco system for obvious reasons but I appreciate the heads up.

He's been in the tank for a good month or so and nothing ill has yet to happen. He started eating after the usual adjustment period of a couple days.

This can work against you also.  I'm not sure where you caught it but say for example, it is a walleye and you caught in on the Ottawa River.  According to the MNR website, from Zone 12, you're allowed to keep 5 walleye with a sports license.  By keeping this fry, you are now limited to only keeping four walleye.

There has been allot of debate about the interpretation of the laws in Ontario, but one thing is very clear:

"It is contrary to the Fish and Wildlife Conservation Act to stock or transport live sport fish without a permit."

The only fish exempt to this are baitfish from the species listed here:

The other thing to consider is what happens if that is a walleye, or other predatory species, and he starts looking at your other fish as a snack.

Whatever you do, don't put it back where you got it if you don't want to keep it anymore...as others have said you could be introducing all sorts of diseases into the water.

If the fish survives and doesn't introduce parasites or diseases, then it will outgrow your current fish tank and cause definite compatibility issues with the tetras. I didn't want to mention it earlier, but keeping wild caught native fish is never a good idea.
