No no :) My betta is safe in his 1 gallon tank. Very active. I hope to ugrade him to 2.5 or 5 even....No ich. Not the saltwater. My freshwater itched but no ich spots. They are all fine for now. Just need better water parameters without a filter...Good, but not perfect. So hopefully that will happen when I upgrade :)
So I have a 5 gallon tank with a filter. Is it right that I should change 25-50% of the water once a week? Also, after buying the fish itself, I should let the bag sit in the new water for about an hour before letting the little guy in, right? Thanks!
