Funny how hard-on we are about tank sizes and fish happiness might as well leave them in the lakes and the stream that they are used to but you will know when his tank is too small and if your anything like most of the keepers on here that tank will be so tiny to you that you will be looking for a bigger tank anyway before the year is up. I wont buy anything under 135 and even thats a waste money unless your getting africans or goldfish
that isn't a bad point, leaving them where they are; the more I learn about the fish and their space needs
