I have them in low tech tanks with sponge filters to high tech with CO2 and power heads, and everything in between.
Have to be careful of the power heads as it can damage long finnage if they don't have an area to chill out, or if it's on all the time.
Nets + Fancy Guppies = a No No also. I use a clear plastic square cup.
