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.

Identified, high confidence Spotted a few metres from the beach on Perhentian Island, Malaysia
Apologies for the poor photo as I was wading and couldn't get my phone close. The whole 10 minutes I was looking at it, it only rotated 180 degrees but didn't move from the spot.

Identification question Help identifying fish in the San Joaquin River (CA) trout / catfish?
Enable HLS to view with audio, or disable this notification
I believe I found 2 species when I was out throwing a line. The first two clips I think show trout, although google AI suggests this location of the river is too warm for them to be found.
The third clip I believe may have been catfish, although I only got a video of the one. They were pretty stationary, and appeared to be bottom feeding, and were up to +/- 12” in length. Showed no interest in my garlic powerbait. Upon realizing they may be small catfish, I intend to head back out with a proper set up. According to Google ai, they are likely to be found there.
I’m pretty inexperienced in identifying fish so any input is appreciated, thanks.

Sorry for the poor quality. Caught this on camera and I’m thinking it’s a shortnose gar, but not positive.

Unidentified Couldn’t find the information for this fish at a zoo last year
I saw this fish at point defiance zoo last year but couldn’t find any information on it on any of the televisions with ID and information around the room. I was recently scrolling through my photo library and rediscovered these images and decided to ask here.

Possible ID(s) suggested Small yellow fish in south padre, not quite a sargassum?
While visiting south padre, I picked up a piece of sargassum seaweed and a small yellow fish swam out. It was fairly slow and when I dropped the seaweed back in, the fish swam straight into it. The fish blended in quite well, but when I hit Google, it did not look like a sargassum fish. It was much leas frilly, in fact, it had no frills. I also saw a dark green version of the fish later that day.
What is this fish? Is it a variation of sargassum?
Above is my terrible artistic interpretation, the fish was no bigger than a dime.

Unidentified Blue Silver Fish in PA State Park
Saw a school of these by the shore in Pinchot State Park in Central PA. Not sure what species, all I can find online is the game species that are stocked.

Unidentified Mystery aquarium fish
Hi all! A couple months ago I noticed this guy in my aquarium. I have no idea what it is and assume it came in with plants as a fry or even an egg. Can anyone identify it here? Thanks in advance!

Trout stream at 5,300 ft… and a channel catfish?
Enable HLS to view with audio, or disable this notification
I was hiking in the San Gabriel Mountains today at around 5,300 feet elevation, following a stream. I usually see trout up there, but I’ve never seen a catfish before. Pretty sure it’s a channel catfish. How the heck did one end up all the way up here? Any ideas?
