what kind of fish

Hello, newbie question. Can you please identify the cichlid for me? Looks like a pretty common one. The LFS guy said he forgot the name of the fish. He remembered the price tag though. Sold it to me for less than a dollar. This cichlid looks quite aggressive to me. Have put it in quarantine tank...

Hi there 2 years ago I went on a trip to the ardennes in Belgium, in a river I caught some minnows but I don't really know which species they are. I have 2 different kinds of them, one is brown on the top with a darkbrown/ blackish horizontal stripe running acros its body and is around 6-7cm...

is this rare? thinking about getting but not if its super common. the seller says its aggresive
