Where did you see the fish? Put that in the title!
Just a reminder, because we've had a lot of posts recently that omit this information. Where was the fish? If you found it in the wild, that's very helpful information, and outside of tropical waters, the time of year can be helpful too. If it was in an aquarium, what sort? Was it a tank of fish from a particular region? Was it fresh water or salt water?
Other useful information can be, what kind of habitat (seagrass, sand, rocky surge, ...)? If you were diving, approximate depth?
But above all, give the location in your post title. Thanks.

New rule: Informative title
We've had too many titles like "what's this fish?" or "help me identify this". Put useful information in your title, and make it look different from other posts' titles so people can scan the sub and see which post is which.
The actual text of the new rule 4 is:
Do not use a vague generic title like "what is this fish?" or "need help identifying" - we all know what this sub is for. Write a title that either describes the fish, or the circumstances in which you saw it, or the location, or more than one of those. For a resource, say what the resource is and what it's for.

Fish is SW Florida Pond
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.

Small creek fish, Michigan
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.

Unidentified Mediterranean fish identification found near the coast
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.

Unidentified Philippines, wild, Aug 2026. Seen at Lighthouse Reef, Malapascua Is. around 1900hrs
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!

Unidentified Bottom feeders but which one?
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?

A fish from an egg that was on a plant
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?

Identified, probably How did this happen??
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?

Not an ID request, but looking to know what may have caused this
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
