Thank you so much for your reply Andrew. I'm still open for other ideas as to what could have gone wrong, but for now I think I'll chalk it up as bad luck.

Thank you for your response. I tested the water with both a the dip stick type and the liquid Master Test kit during the 5 days he was not eating both kits provided the same results. Our tank has been up for about a month now. We had it running for 2 weeks prior to putting our fish in and I've been using API Quick Start and Aqueon Betta Bowl Plus for each water change. There is almost no flow in the tank. The filter is adjustable and hardly moves the leaves on the plants when the water runs off the opening.

New fish owner here. When we got our betta he was super active and followed us around the tank and readily ate. He stopped eating about 5 days ago became lethargic. I thought i may have over-fed him pellets and thought he could go a day or two without eating. Day 3 of him not eating he started hanging out behind the filter and near the heater. Day 4 of him not eating and being lethargic and after some research, I thought this may be due to low temperature (75F) at the time so I turned up the heater. It measured about 77F and soon and he started to move around more. About 30 minutes later he was going between breathing heavy on the bottom of the tank and rushing to the surface and then back down. Yesterday afternoon I did a 25% water change with tempered water because my test kit was reading a pH of about 6.8. I went to get a cup of coffee this morning and found him dead on the bottom of the tank. Throughout the last 5 days I have been sampling the water daily and have had no difference in what I have below with the exception of pH. Other things to note, I have a Ramshorn Snail in the tank that's been laying eggs like crazy and am wondering if this is a factor. Also my filter is running very slow and dumping onto some plants so I don't think a large current is an issue. We have an aquarium gravel cleaner for cleaning the tank and a designated bucket for adding water back into the tank as to not introduce chemicals. I've been feeding him Omega One Betta Buffet Pellets. Water readings last night at 10pm pH: 7.0 Ammonia: 0ppm Nitrite: 0ppm Nitrate: 5ppm Hardness: about 75ppm Chlorine: 0ppm Alkalinity: 0ppm I've attached a picture of "A the Fish" as of last night. Any advice is much appreciated.
