Does this guy look ok to you?

[Cheezasaur]

I posted a question on reddit and had a pic of the fish - was unrelated to my actual question - and someone commented that he doesn't look healthy.
I found this page after that so thought it might be more legit than reddit, I don't know, I'm just desperate so I'm seeking help everywhere.

Betta fish July 28

I got this fish 2 weeks ago from my father in law's house. He passed away mid-June and no one else would take the fish, so here we are.

He's been swimming around ok, occasionally lazing around; I don't know how much he's supposed to eat but he does eat some every day. Not much today though... I don't know anything about Betta fish but I think he's ok?? Although I am worried that he seems really droopy...

I tested the water 2 days ago and it was basically perfect, which was surprising to say the least. (I don't know when the last time anything was done to his tank but it was definitely not after the end of May, as that's when my father in law started going to the hospital a lot.)

This video was taken after I got home today and noticed he has this weird bit on the tip of his top fin. I had just put a heater in a few hrs before and wondered if that had anything to do with the spot on his fin as it wasn't there earlier today. I wonder if I heated his water too fast, as when I left it was around 79 and when I got back it was 82 and he was sitting beside the suction part of the filter which I thought was weird...
*sigh*
I am aging 5 years every day since getting this fish.

Well the betta definitely looks bloated I can't tell if his scales are pine coning or not. If you have photos of the fish from farther away that might be helpful as well as posting exactly what your parameters are and what your feeding schedule is.

Your beautiful betta doesn't look happy, have you tested for ammonia levels? this is a separate test and bettas must only use bottled spring water or special betta water from pet store.
Only change a little less then half to do water changes weekly,
I use a microbe-lift XTREME water conditioner even though I use crystal geyser spring water for tank water.
I also use imogitarium stress treatment, it helps bettas with there natural slim coat & also tints the water to there natural habitat.
Bettas don't like to much motion in there water I use Doxtech 4in1 fish tank filter it comes with rainfall pattern for water flow output, I have a 6 gallon long tank so I use two of these filters one on each end both rainfall pattern for outflow turned up all the way they can be fully submersible.
I don't run a heater cause my tank stays at a 78 degrees.
They love floating mirrors and the love a basketball hoop that suction to the side they will go swimming in and out.
Bettas need to be able to forge on bottom so I use a very fine sand blue & black. Also I hve 2 moss balls, and two suction cup plants.
I raise bettas and breed them. They live attention they live to be out were they can see the action. U can train them to jump threw hoops and they love to play with little sinking balls that helps to forge on the bottom. I hope this helps.

I would not say this is true necessarily. If you where keeping more rare wild bettas then yes you might want to use a more specialized water. However for most bettas you find in the local petstore the water that comes out of the tap is fine. Unless of course the water coming from your tap is not safe for some reason.
