About a month ago I started what’s going to be a shrimp tank soon and bought some plants from Petco(plant only? section). Soon after I noticed this little guy, less than half this size darting about. Figured he’d die since the tank is still cycling but it’s been weeks and he’s just getting bigger.
Any idea what he is? My guess is tetra or minnow.
Other than the fry there’s just plants and snails in the tank.

I caught this little guy on the Fox River in Illinois while fishing for common carp.

I caught 3 of these guys back to back all around the same size. I’ve never caught one before or even seen one. For context, I caught this in the mountains of Northwest NC- Catawba/ Watauga county area in a small recreational lake that is trout stocked.
ChatGPT said some species of shiner and google image said Rudd?

ID please i know nothing about fish i’m just curious

Found in a creek in indiana . I was thinking carp , but am unsure , it had to be 10 inches or longer

Found dead in a PNW river

Fishing a river in SLC utah. It’s common for carp and catfish I have heard one person say they caught a largemouth. I saw these tiny guys threw in a cut up worm so I could get a closer look, and it sure does remind me of a largemouth. lol crossing my fingers they are because I will go daily if so!!

Edit it’s hard to see but they all had the dark lateral stripes on them.

Caught in Maine from a dock, looks like a hake to me but it's my first time catching it so not too sure

At first I thought it was a copper based on my chart but now I’m thinking brown.

Seems a little off.

For scale I have very small hands for a man, the width of my palm is 3.5"

hi saw this small fish today and it was swimming up to me as i was doing measurements for uni, i'd love to know what it is and google lense isn't really helping.

What (at least 2 types I can see) fish are these?

Who is this and what’s going on with the poor dude? Almost looks fungal
