[DanDanUK]

Very close, it is sold as a fw barracuda, or cachorro. now which species? not the falcatus, notice the horizontal stripes.

Acestrorhynchus isalinae

My turn.. What kind of fish are those 2 in the middle. The ones with the buck teeth?

That is two very wierd looking fish.

 

[DanDanUK]

YEAAAAAAAH i got it right !!!

My turn.

This fish is native to europe:

Dan dan the etc, is correct, Isaline's cachorro, a relative of the falcatus, both sold as fw barracudas, this oneis more attractive and gets a little bigger, about 14-16". Very predatious, likes a small school, likes a little salt and a neutral ph. It is from Guyana I believe. Dan's turn to post a picture.

 

[DanDanUK]

sorry i was a bit eager so i jumped the gun a little so you can start to guess .

 

[guppy]

Petromyzon branchialis (the european lamprey also called prid or pride), I would need to see the teeth to be absolutely sure.

 

[Fomoris]

Yes, it's a "lamproie" (in French)

 

[guppy]

Well Dan is offline and I know that I am right as far as the lamprey part goes and without a tooth pattern can't be absolutely sure of the species except that it looks way to bright and large mouthed to be an english brook lamprey.
I'm going to take a gamble and post the next picture, if I'm wrong we can disregard it.

Here is my chosen fish, common name and scientific name please.

Serrasalmus elongatus, pike piranha.

That should be in the piranha forum though.
