just picked up another lil spotted. i have 3 now. 2 spots, and a weeksi(i think thats how you spell it) i have them in a community tank right now. some canios, a rainbow, and a large cray, they all get along great.
these guys can get a maximum of 8'' but it rare that they get that big
a 40 -50 would be fine for a long time they don't swim a ton unless chaseing another fish so a nice planted 40 gallon breeder would be good for allmost life and a 55 would be fine for life
