Hi, my Betta Pierre and Fred the Parrot Fish (two tanks) have developed ICK on their tails and I treated them with ick fizz tablets but the ick doesn't clear up. I also used almond leaves in Pierre's water and I do water changes 25% every day with filtered water in tank temperature (78F) and the ick is still present although I throw in another tablet. Does any of you know of anything else I could do for Pierre and Fred. They are both energetic and attentive, they eat, swim and act normal. It's a 1 gallon tank for Pierre with airstone, no filter, no heater, but in the middle of the office with no draft or radiator contact and a 3 gallon tank for baby Fred with bio wheel filter and air stone, no heater but the tank maintains 78F. Thanks.
