Im not saying any fish are easy to keep, please dont think i am, im just saying they are by far the hardiest that i have seen compared to other fish, my sister has kept a betta in a 2.5 gallon tank with no heater and barely any water changes for about 3 months now the poor thing, but it stills alive, not thriving by any means though because my sister doesnt care. Most tanks are like this, with the person just really not caring.
I would agree, its my favorite animals to keep, and you have to be dedicated to them to keep them thriving or you wont enjoy the hobby, i was just stating a hard to kill fish :/
