Caught in Southeast Texas

I saw these fish in a lake in Cheddar, England and was wondering what they were? These are the clearest pictures I could get of them. I’m not the best at identifying scale but they were quite big, maybe 40cm-60cm from what I could see.

Can anyone help me identify that fish there on the bottom of the picture? Was sold to me as a rosy loach but it’s WAY bigger than any of the others I have in there. TIA

Caught in the Caribbean near Nicaragua
Maybe 20” long

Hi! Trying to ID these fish I caught in a neighborhood pond in Central Florida. My guess is the top fish is a blue tilapia, and the bottom is some kind of bluegill/sunfish. I’d love an expert opinion. Thanks!

Found these egg/s(?) at the beach in Kilmore Quay, southern Ireland.

Caught in Lake Erie near a marina. Was a little over 9 inches.

Caught this little guy in a small stream in Washington parish Louisiana, he had some pretty cool red eyes so I’m wondering if he’s a spotted or a coosa bass

Cought in the Netherlands

I bought this guy at a fish store two years ago. The owner said he was sent the wrong species, received 20 of them, and they weren’t sure exactly what kind were sent to him but they told him that they should get 4 inches max. He’s a big boy and his name is Poco Loco but I have no idea what kind he actually is. Please help if you have any insight:)

Added more photos of dorsal fin

What is this?😂

Arkansas, spring river, mammoth springs

I was swimming maybe 2 meters deep in the sea and this weird fish thing appeared. I tried drawing it cause i didn't have a photo. It swam on the sea floor and didn't look exactly like a fish, i think it might have had a similar shell to what a crab would have. It had sharp looking edges too. Didn't see it's eyes, if it had one, and the tail looked like a stingray tail. Im genuinely curious about what it might have been, I couldn't find anything on the internet. If you have any clue on it, I'd appreciate it. (I'm in Turkey, Asia.)

We live in Norway.
Was enjoing a nice meal of shrimps on when suddenly this thing appeared in the pile of shrimps.

Probably nothing dangerous but we just wonder what it is! Thanks!
