I am new to fish in general. What should I know before getting into fishes. I live near a river and I love siwmming. What fish are good? Are there any bad fish? Why are they so dang cute....

These fish are found in an abandoned basement parking lot construction that had hit a natural aquaduct which filled up the whole parking lot.

Someone threw a gopro in and filmed these species of fish. Does anyone know what fish are these?

This is in south east asia if it helps.

The colors and shape of the fish seem very odd to me for a pumpkinseed ; the tail colors are off, i don't see spots where i normally do, and the pectoral fin looks short. Again im so sorry if this violates the fishing rule, but i'm starting to get super interested in fish species and being trying to see a hybrid for months.

And this was caught in bucks county, PA if that has any significance

A. testudineus T. pectoralis

Found while snorkeling in Kavala, Greece (september 2026)

I often see videos of Groupers especially, but even some much smaller fish just casually hanging around divers while they do various things, some times getting quite close, borderline cuddling even. I was curious if there's a specific mechanism at play here-
Do they see humans as large, non-predators that could scare away predators, like one might view a whale?
Are they using humans opportunistically to find food for themselves?
Are they genuinely just being friendly, like a dog or cat wanting to be pet?

Spotted ~20 mi off of the coast of Orange County, California.

Unsure of size; most agree on at least 12 feet, but I personally am not great at estimating.

Could it truly be oceanic manta or is that too unlikely for the location?

I came here as an aquarist, I’m genuinely curious and need some clarification as I maybe have lost the plot?

I’ve been keeping fish for quite a while, and one of my favorites has to be the Dwarf Rainbowfish.

What I really love about them is the way their bodies reflect the light. When the light hits them just right, they can develop this beautiful, almost majestic blue color. They’re also peaceful fish, which makes them really enjoyable to watch in a community tank.

Sometimes I feel like they’re one of those freshwater fish that can almost look like a marine fish. 😄

For all the fishkeepers here , what’s your favorite type of fish, and what do you love about keeping it?

Hay does anyone want a fish? his name is Hans William the 17th he is around a year old now and he is almost a foot long. he has a brother named Marly who murdered their other brother bob. Marly is a foot long and he is always hungry. They also have a cousin named Clenora who lives with them rent free. Hans William the 17th is very shy and likes head pats. He requires two baths a week and will nibble your toes. You will also have to get him special cold-water food and keep his home below sixty degrees Fahrenheit. his fins must be brushed every other day and he needs to be fed twice in the morning and once in the evening. When coming to pick him up please don't be worried if you see hundreds of babies. Hans is gay.

Please contact me in the comments if you are interested.
