I will soon get a RES, probably a male, and will raise him in a tank. I will always feed him in a feeder tank, but, how often should I clean out his regular tank? My procedure for cleaning out his regular tank i guess would be to remove around half the water, use a PH strip to check to balances of the water, and fix it accordingly.
So how often should I clean it, and if I'm not doing it right, how else should I do it?
