Spanish For Children

Spanish children’s song?

Last year my spanish teacher had us sing children’s spanish songs every Friday and one of them was called Los Pecesitos but I can’t find it anywhere on the internet. Does anyone know the lyrics to this song? I want to use it for a project I am working on. I think it starts out “Los pecesitos estan en el rio nadan, nadan, nadan, nadan, nadan.”

I know a song that say PERO MIRA COMO BEBEN LOS PECES EN EL RIO….BEBEN Y BEBEN Y VUELVEN A BEBER….. but its a christmas song i don’t if its the one ur looking
