Help with ich and oto discoloration

[JacobB]

Hello,

I made the mistake of adding otos to my 10 gallon betta aquarium without quarantining them. The otos ended up having ich so I have been treating with ich x for the past 8 days (1 tsp every 24 hours with 30% water changes). The fish look a lot better but some of the otos still have a few spots on their fins and body. I thought ich x would be able to fully treat ich within a week and now I'm worried that this treatment may not be enough. I also don't want to treat this tank too long because I've heard this medication could be dangerous. Do you guys have any advice on what I should do?

Also some of my otos are developing white patches on their head behind their eyes and I am unsure what this is. I attached a picture of one of the otos. Could this be caused by the ich or medication? What is it? Thanks for your help.

It could be a bacterial infection from any open sores that they may have. You can try using Maracyn. Helpful in addressing any fungal or bacterial infections that they may have.

Should I use both ich x and maracyn at the same time? Or should I finish treating with ich x and then use maracyn?

Ich x and maracyn are safe to use together according to aquarium coop.
