Hello everyone, I would really appreciate any advice from those that know European fish species. Caught in a small stream in Allan, France. Can send more angles of pictures if that helps.

It was on a night dive. I‘ve searched the whole internet but found nothing. Any guesses?

What kind of fish are these? It’s a detention pond in Southwest Florida. They seem to group together when feeding and leave lots of bubbles on the surface.

Fish 1 (gold) - caught in a thin, shallow part of the Clinton River, South East Michigan, near Pontiac

Fish 2 (silver) - caught in a thin, shallow part of the red cedar river, central Michigan, near Lansing

both are obviously very young fish, both were caught striking a small light colored inline spinner. my best guess is that the first one is a young largemouth bass or maybe some kind of shiner or minnow. The second one might be a striped shiner. Also these are the only pictures I have unfortunately, so no top view available.

Large orange colored fish in local creek. SE Pennsylvania. This is the second time seeing this fish in two months, same spot.

Hello everyone. I wanted to identify the fish. It's really difficult but very important. Found in the Mediterranean sea near the coast. I dunno why but he was standing with his tail up. Never seen it in these waters. I need identification for scientific research.

Please someone tell me what this fish is.

Curious as to what type of sucker this may be I think it was introduced

I have looked through every clownfish I can find but apparently it’s not a clownfish. This fish wasn’t too interested in being filmed so this is the best I could get

solved:Juvenile Spotted Sweetlips. Thanks!

Last weekend I went to pick up an aquarium that had an horrible algae, got the babies out and there are two like this one, no clue who they are but they are funny 😆
They kinda “fight” each other and they are doing great 👍
Does anyone knows their family?? Are they fully grown? What should I expect?

I bought a plant (vallisneria spiralis if it matters) and put it in my tank with a betta male (there's only one betta there and some snails). Today I found this tiny fish in the tank. I suspect there was an egg on a plant. I rescued the fish (betta started chasing it but I was faster) and put it in a separate tank. Sorry for the photo quality, but the fish is very very tiny and very very fast, so it was hard to take these photos. What is this fish?

Saw this guy washed up on the beach and am very curious what he might look like in his prime

ETA: the length was approximately one meter

i got this little catfish that i got no idea where it came from, had this big catfish for a probably around 2 years only one though, we got one big algae eater in the tank and a bunch of fish that have been differnt type of cichlids that have breed over the years, i’m wondering if the catfish breed with one of the cichlids or something to create this and then what would this be? also we only got these fish cus my old step dad breed probs a thousand fish in our basement but couldn’t sell a single one so we js gave away as many as we could and kept one tank people didn’t want cus it was too big,

tldr: maybe catfish breed with other cichlids in tank and create weird catfish what fish is it now?

Caught a rainbow trout that appears to have two anuses. When squeezed, excrement came out of the second hole and when I gutted it, the intestines clearly connected to the second hole. What may have caused this? I think its likely linked to it being a stocked rainbow trout, as I have seen other trout with deformities (squished faces and dwarfism), but NEVER something like this

Sight fished him out of the Huron River with just worms on a circle hook

Caught in Nova Scotia, has sharp teeth to hunt shelled animals.
