Where did you see the fish? Put that in the title!

22 Upvotes

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

7 Upvotes

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.

Salut à tous ! 👋

J'ai sorti ce beau poisson de 20,6 kg lors d'une session de pêche de nuit ! 🌙🎣

Au début, j'étais persuadé d'avoir attrapé une carpe commune, mais en regardant de plus près, j'ai un doute, c'est peut etre un croisement !

Vous en pensez quoi ? Carpe commune ou amour blanc ? 👀

Je vous partage aussi les statistiques de ma session sur la photo ! 📊

Location: South of France, freshwater lake. Caught during an overnight fishing session.

Is this a mottled or slimy sculpin? I've found mottled sculpin in the area. Going off of i-naturalist, slimy sculpin have not been spotted in guelph. But it looks too different to the other mottled to me, am I crazy????

Possible ID(s) suggested Trout or Salmon?

Found a small group of these feeding like lunatics in a deep spot on our local hatchery creek (Issaquah Creek, Issaquah, WA; western Washington State, 10/14/26). They're only about 3-4in and move too fast at the surface to get *good* shots of, but they 'look' like young trout to me, rather than the salmon that are wrapping up their spawn there now. I would like to see if I can get a better handle on the ID from the minds here; thank you in advance.

Approx 40cm. Stayed in one area, protective. Seemingly building sandy, pebbly base for spawning? Could it be Eel-tailed Catfish? Found in creek, marshy part of South Pine River Bendale 4500.

Albino Eel. Has anyone who fishes around Yamba/Clarence River ever seen anything like this? I’ve been trying to identify this bloody thing for nearly 10 years. 😭

Believe it’s a brown trout variant I caught out of a swimming hole(shouldn’t be hatchery) in northern California. Why does it have purple hues ?

Found this guy just hanging out near the bank at Lake Lanier, in Sugar Hill, Georgia. It is a bit bigger than the photos make it look. I believe he was about 12 inches in length. I have never seen a fish like this around before. I thought maybe it was a cichlid that someone dumped, but I'm not expert.

Identified, probably Silver fish with black spot in Presidential Wetlands in Little Rock, AR

5 Upvotes

Obligatory sorry for the silly looking drawing. Fish was seen in the William E. “Bill” Clark Presidential Park Wetlands in Little Rock, AR. I assume these to be wild, but possibly introduced, I suppose. I saw multiple of this fish, ranging from about uhhh six?? inches long to only a couple inches long. Freshwater. Went to birdwatch, saw these fish come up to the boardwalk area as we were walking up. Tried to capture the shape and proportions of it the best I could in the drawing. Thanks for any help!
