Welcome to whatsthisfish!

Yes, this is a complete ripoff of whatsthisbug.

If you have a photo of a fish you'd like to identify, submit it here and we'll see if we can figure out what the hell it is.

In your post title, please include where the fish was, and when, or at least the source of the photo, in your post title. If it was in an aquarium say what you know about the type of tank it was in (freshwater or salt? does it cover a particular region or type of habitat?)

Flair your post! Click "flair" at the left below the link. Update flair if someone identifies your fish or suggests an identification.

Before you post, we are not going to kill it with fire, so don't ask (or shoot it with an arrow, or throw it on the bank) Thanks.

When you comment with an identification, include your reasons, so others can learn from you how to identify similar fish in the future. Please do not make random guesses. The goal of this subreddit is to provide positive leads. False leads are counter-productive.

Please also cite/link a source whenever possible.

Consider /r/species for non-fish aquatic creatures (or any other sort of living thing).

Resources that can help people identify fish are also welcome, within reason and moderator discretion. Otherwise, off-topic posts are subject to removal.

What is this fish called?

I assume the big one is the female and the small one is the male. They’ve had a few babies together already. Does anyone know what they are called? They seem kind of social, it almost seems like they get excited when they see me come over to them lol. I’d love to learn more about them if I can!

I was swimming and found this

While swimming I came across a head in the see. It was about 300 meters off shore. The area is tropical and the head is about 60 cm in length.

Since this is the biggest thing I have seen after swimming in this area and it's just the head I started getting curious what fish this could have been.

Saw on INAT. Photo search on Google and said no results. Cichlid? New species?

This poor guy ran into my kayak on the river. A number of dead fish floating downriver along with him.
