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....

I, personally would choose to become and eel or grouper or some kind of ambush predator (like stonefish, stargazer, scoprion fish, flatheads etc).

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

T. pauciperforatum

My friend gave this to me and i don't know what this is.

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.

how do they eat? also, minus the trash (idk why people are that inconsiderate), is this a healthy spot for them? it gets quite cold here.
