How long can Ich live?
I was hoping if someone can tell me how long Ich can live. I currently have a spacious aquarium that's been running for years that use to have Ich almost a year ago. It use to be a goldfish tank, but the goldfish moved out a long time ago. Currently, I turned it into a planted aquarium that flourishes with different species of Anubias + some random guppies and Otos. None of the current residents have showed any signs of Ich (Ever) for a dozen months, but I'm just being paranoid. Paranoid that even if Ich can't penetrate any of the fish because they are too healthy, but yet can lie dormant and wait until the opportunity presents itself!
I want to add Clown Loaches to this 150 gallon, and I heard they are susceptible to Ich. Can a tank that had ich long time ago, STILL have it even if the parasite hasn't showed any visible signs? Is there a way to see if Ich's in your aquarium without waiting for it to happen?
I WAS thinking about adding Red Cherry Shrimp instead of Clown Loaches, but CLown loaches look like they can be super fun to watch and interact with!
