I would lean on this being a fungus, but as I am no expert myself I would wait for someone else to also come to that conclusion. What I would recommend in the meantime is moving the affected fish to a quarantine tank, if possible, and following the salt treatment guideline provided by one of aquarium coops blog articles (https://www.aquariumcoop.com/blogs/aquarium/aquarium-salt-for-sick-fish). If that doesn't work and your current medications also appear to not do anything, I would suggest switching to medications with other types of active ingredients (so no maracyn, as that contains erythromycin, and avoid ich-x's active ingredient of malachite green). I hope others here may be able to better narrow down the disease for you and I hope your fish do better!

The plant is grown. The problem is that the bulb/root portion does not want to rest at the bottom of the tank.

I've heard that too, but I got the lily from a lfs and its fully grown already. Hence why I would be confused if it is no longer viable.

I am running into an issue where a recently-purchased, dwarf aquarium lily refuses to have it's bulb sink to the bottom of the tank. Any recommendations besides weighing it down? Will it eventually sink on its own? Is something wrong with it? Its been roughly 3 days since the plant was added to the tank. Note that the plant is not just the bulb but also has many leaves and roots.
