well
in september and october
we often get very hot days
then very cool nights
the most common way to get a fish disease called ICK
is from a temperature drop
so be sure to check your thermometer on your aquarium every day to make sure your heater is working properly
most tropical fish aquariums should be at a consistent 77 degrees F.
also closely observe your fish daily
to make sure they do NOT have small white dots
Ick is easy to cure
but is fatal if not treated promptly
