Can anyone id These fish

where are they from (what part of the world)
how big are they (approx) in cm or inches
freshwater I guess?
any extra info may assist.

the middle one looks like something I may know if you can answer the above please

@Pootle these were in a tank that all it said was Pennsylvania so I can assume they are Pennsylvania native. They are also small fish

thankyou for the info. being UK based I can only say....

the middle fish looks freshwater and the dorsal fin as you can see is large for the individual. It looks like a member of the Salmon family and to me it resembles a fish in western Europe known as a Grayling. I refuse to use scientific names here, as they are irrelevant on a fun forum and often hard to pronounce!
Please bear in mind this is my opinion only, have fun!

if salt water just bin the above, hence asking for as much information as possible

I used to live in PN,
This fish sort of has a resemblance to a White sucker, A species that I have seen in the wild. It matches the arrangement of the Fins, and the position of the face and Eyes are identical tho the ones I saw in the wild. So I think your best bet would be Catostomus commersonii.

@CheeseChameleon2007 I dont think Its white sucker I have seen a white sucker this fish Smaller. I am not good at identifying fish tho so maybe the fish I thought was a white sucker was not and this is the white sucker

@Elephantlover Sort of hard to tell from this photo actually how big this fish is, but I'll take your word for it. Possibly a species of Minnow like Exoglossum maxillingua?

Anway, I won't continue to help in this case, I have made such a terribble fool of myself, I have proven that I can't identify pretty much anything.

@CheeseChameleon2007 I am in the same boat I have a hard time identifying any fish or reptile. however your latest id could be the fish from the pictures I have seen on google
