20 gallon tall sorority
So I have a 20 gallon tall tank. it has the same footprint as a 10 gallon, but it is like two ten gallons stacked on top of one another.
I was wondering how a sorority would work in there and how many females you think would be appropriate for the size. I know in a 10 you probably wouldn't want more than 5 due to water quality, but do you think with the extra height space and amount of clean water a few more could comfortably live? I wouldn't put as many as I would if it were a 20 gallon long, but do you suppose a middle range of females would be fine? What number would you feel most comfortable adding?
Thinking about having a NPT. What do you think?
