Thats pretty much what I thought I just wanted to double check to be sure. Thank you for your answer I'm just trying to figure out some ideas for this tankashleysomething;3034076; said:I would say no, not for life, although it depends on footprint and filtration, as well. If you are only keeping a couple Potamotrygon hystrix or P. scobina then I would say 6'x3' should do nicely. A 180 makes for a nice growout tank, but just be aware that there is no way that they should be living in that as adults (if it is standard footprint). If you want to keep rays, try to go as wide and long as possible.
