Quarantined Blue Panaque Pleco L239 from online retailer

[Landon]

Hi, I just received this Blue Panaque Pleco from an online retailer yesterday. I started the med trio as soon as I got him in a quarantine tank with a cycled sponge filter. Today, I am noticing some disease. 

I would love some help with these questions:

1. This is my first time diagnosing disease, but I'm guessing that I'm dealing with Ich and Fin Rot. Does that look right?
   
   
    
2. I'm piecing together information from Co-Op videos and other forum posts, but I'm thinking I should do a 30% water change and start treating for just these two diseases using Aquarium Solutions Ich-X and Mardel Maracyn. I guess I should now follow the package directions for both of these? 
3. Can they be done at the same time either though the packaging for Ich-X says not to mix medications?
4. When should I feed him? I know this species is especially susceptible to malnutrition and I don't know when he was fed last. I've had the cycled sponge filter in this tank for 5 days, and I've been feeding a mystery snail in there to keep it going. 

Thank you in advance for any and all help! 🙂

What I would do is water change out the other medications and just treat him with ick x and I would add a small amount of aquarium salt 1 table for 5 gallons as ich causes massive electrolyte loss and the aquarium salt will add back in essential electrolytes I would also feed him during treatment to it give him energy to help fight off the ich as ick x requires daily water changes that will help maintain good water quality

That plan sounds good to me. And maybe the salt will help the fin damage I'm seeing? Thank you very much for the input @Colu!!

Hmmmmm I'm not convinced that's fin rot, necessarily. If it's a small online retailer you can try reaching out to the seller and asking for advice on what you're seeing. I've found small independent retailers to be quite helpful about these things. Good luck!

EDIT to add: I wouldn't do anything other than salt and water changes for the fins. Not sure I'm looking at ich, either. There's some spots but it's not a lot, and if they aren't spreading like wildfire in a day I would not think it's ich at all.

Thank you for your insight @laritheloud! It's very possible I'm being hyper vigilant. Maybe I'll stick with the med trio and try out salt if I see these issues progressing, but he is looking pretty good today.

This guy died today (day 3)... I was starting to think that he looked healthy. He didn't have any Ich spots, but he left behind some weird looking poop. Maybe it was parasites? I didn't try anything beyond the med-trio. If I could do it over again I might have tried feeding him earlier in addition to salts for electrolytes.

Sorry to hear he didn't make
