Man wish I would’ve taken a pic before disposal of them, could’ve identified the sickness possibly. But yeah not the best start to the hobby, kinda off putting haha but I’m sure it gets better. Thanks for the help and will do researchSorry to hear about the other Clownfish, that's a rough way to start out in the hobby, but unfortunately all too common.
I'm not so sure if this is Ich, I think erratic swimming points more towards something like velvet, but it does sound like you have a fish disease organism in your tank, and the typical method that's often advised is to allow your tank to go "fallow" or "without fish" for an extended period of time. I believe Jay H. recommends as short as 45 days for Ich with an elevated tank temp (81F), but I think he advises a full 60 days for Velvet. You could do 60 days just to be safe. In that time any fish parasites will die off without a fish to complete their lifecycle.
Then going forward, and as mentioned above, you may really want to look into either purchasing pre-quarantined fish from a reputable vendor, or QT'ing your own fish before adding them to your display tank. Here's the correct R2R QT protocol that I like to follow:
