Hey everyone, I just transferred my neon tetras to a bigger tank (20g to a 40g) and most of them are now suffering from fungal infections (or at least what I think are fungal infections; white cottony extensions on different parts of fish).
I previously had them in a tank with dalmation mollies who suffered from this when i first moved them into the tank from the store. I treated with tetra lifeguard tablets and it was gone within a week. I moved the mollies that previously shared their 20g into the 40 gallon a week before and they didn't have a fungal outbreak.
when I was looking online about it, many places say fungal outbreaks can be caused by stress, dirty water, and/or weakened immune systems. Which would make sense that they would be stressed after a big move to a different environment.
a couple of people said that fungus will always remain in the body of the fish but will break out/become active when stressed or when immune system is compromised/weakened. I just wanted to see what y'all thought about this?
If this is true should i just wait for the fish's natural immune response to improve in their new environment? It already seems like on a couple of fish the cottony parts are getting smaller, but for the majority of the fish the sites are not shrinking or growing.
