Betta fish care

White spot ich treatment fish

White spot ich treatment fish start with quarantine and medicine made for ich, used exactly as the label says. Raising temperature slightly can speed up the parasite's life cycle for fish that tolerate it. Remove activated carbon, and use caution with shrimp and sensitive fish.
