If you want to see my success;
I have combatted ich twice now but both times I’ve overcome it by feeding and keeping a cleaning station with shrimp and this time I added a cleaner wrasse. I’ve also managed to have fish that don’t eat thrive in a reef as they have plenty of food sources and are in a somewhat more natural environment. They also have other fish that feed to help them along.
Here’s just a couple of my fish, the Foxface and CBB are 4.5 years old. Infact, most of my fish are 3-4 years old.
