I'm sure this is already somewhere on the site, but I can't seem to find it right now. So, what temp is best for fantails?
-i have read that when treating, you should bring the temp to 80, but what about normal everyday temps?

Generally 75-78 is considered a good temp for fancies. They can handle temps much lower, but a lot of people like to have a heater anyways to keep the temp more stable. They can also manage in temps that are higher. My tanks top 80 at times.

cool, thank you. I have a heater that came with my tank, i've been keeping it at around well, ironically 75-78, so i guess that's a good thing!
thanks again!
