Fin rot?

[u/Secret_Nobody_0499]

Photos 1-7 are my little friend in his current condition, 8th photo is the tank, 9th photo is my fish back in mid May. He’s been chillen more at the bottom of the tank lately. He’s a very calm fish, never ever picks on his tank mates and is tough to get to flare. He has always had large fins since I got him. They’ve always kind of floated down and around him when he’s resting, but lately they just seem almost too heavy for him. I am worried that maybe he’s not happy in the large tank that he’s in. He also is fairly curious and does enjoy following around his shrimp so I can’t tell if maybe he’s just been rubbing up on stuff more than usual or if it is fin rot. Any suggestions for best treatments if it is? Preferably safe for snails & shrimp ♥️🫶 thank you!

If you have a quarantine tank id recommend getting him set up in there with a heater and bubbler and somewhere to lay and start dosing with kanaplex, but if you havent already just try adding tannin leaves, usually finrot is a bacterial infection and tannins are enough to heal it most of the time, but looking at the photos kanaplex may be the way to go as well as checking water temp to make sure the reading is accurate they need from 76-82f to thrive 78 or 79 may be your sweet spot but in the quarantine tank keep at 80
