Grass Carp change as they grow, but key features stay the same. Look for no barbels, low-set eyes, dark-edged scales, and no keel along the belly.

Some native and commonly caught fish can resemble juvenile invasive carp at a quick glance, especially small silvery baitfish and deep bodied forage fish.

Another interesting fish. I've never seen a fish crawl like this one did. Possibly Scorpionfish or stonefish?

A blurry cropped photo of the shoal of small fish (6-8" at a guess) I spotted jumping out of the water of a freshwater stream this afternoon.

A cropped close-up of one of the fish starting its jump.

Another blurry photo of the same fish re-entering the water.

Another cropped close-up of another of the fish 🙂

I'm not supposing that these stills I grabbed from the original video will help much (of course, the automatic downsizing here ruined it 🙄), but you never know🤞 #FreshwaterFish #FishSpecies #FishIdentification #FishID #Kent #England #UK

The last time I saw this mystery fish clinging to a drifting #pyrosome was almost exactly a year ago. My best guess is perhaps it’s a young #marine #bream of some sort???

Throwback Thursday to last summer for something else I did "Throwback", anyone else know what kind of fish this is?

The coloration of Princess Damselfish (𝘗𝘰𝘮𝘢𝘤𝘦𝘯𝘵𝘳𝘶𝘴 𝘷𝘢𝘪𝘶𝘭𝘪) presents an intriguing pattern, wherein hues slightly differ among individuals; some display predominant blue tones on their bodies, while others lean towards yellow or orange shades.

Signal Goby flaunting its dorsal fin! 🚦 Signigobius biocellatus has a fascinating feeding behavior! They sift through sand in search of tiny invertebrates, expelling the sand from their gills.
