Guppy Swimming at bottom of tank

[Clare1125]

Hello Fish Friends!

It's been a while, I haven't had any trouble with my fishes until recently. I have noticed one of my guppies has been hanging out at the bottom of the tank these past two days. He doesn't have heavy breathing, fins aren't clamped to his sides. He just hangs out on the bottom when usually he wouldn't. Not too sure what's going on but I'm just hoping he's ok and I'm the one freaking out.

Thank you in advance!

Water parameters? Tank size? Full stocking? How long have you had him?

Going to do a water change today. 10gal. 2 cory cats, 6 guppies, I've had him since about late May.

What’s the readings for ammonia, nitrites, and nitrates? The corys should be in groups of 6+ and 4 in a 10g because they’re schooling fish.

Ammonia: 0.25
Nitrite: 0-0.25
Nitrate: 10-20

This fish is the only fish that's acting like this all of the rest of them seem to be doing fine but I am noticing a change in their poop. Not sure if there is a parasite but I did a tank cleaning of 75% and when they pooped, two guppies had white stringy poop and the others had regular. The one that has been hanging out on the substrate has had a mix of both. Yesterday when I did the tank cleaning I put in Imaginitarium Bacterial Infection Remedy and will be doing it every other day for the next week. Should I also be doing a water change?

Here are some pictures of his tail. I think he has ICH.

It’s hard to tell. Does it look like he has bumps protruding from his tail?

Hello fish friends, unfortunately little Phillip did not make through the night. He lived a good couple of months, breaks my heart but I could tell he was suffering the last couple of hours.
Thank you for all of your guys' help. <3
