Any ideas would be helpful!

Water changes will never hurt. I really don't like manmade products in aquariums.

I'll try another one and see if that improves anything

Usually a high PH means you have hard water unless you have my water lol... It could be that your fish are starting to react to the hardness of the water... I would use a liquid test kit such as API to get results

Yeah im pretty sure my water is hard. But would it still affect them if they were born into hard water? Pretty much all of them were bred in high ph water

No, its in their DNA to be in soft water. Hard water species have certain parts in their body directly for hardwater. If they were born in hardwater they may last a bit longer than an adult softwater species being moved to hard water but they will still die. A lot of people do think that if they are born in hardwater that then they are used to it, but you can't and shouldnt house a softwater species in hardwater or a hardwater species in softwater.

They’re ancestors were in the same water for hundreds of thousands of years until humans started transporting them around the world to places where they’d hadn’t occurred naturally. Sometimes these places have similar water sometimes not.
Hardwater contains minerals that hardwater fish have evolved to be able to handle and soft water fish havent and vice versa.
A few generations in different water isn’t easily surmountable by most fish.
My PH is 8 and hardness PPM is 340 iirc. I’ve chosen to taylor my fish choices to suit due to the guilt brought on by my unknowing fish selections in the past.

Best of luck with them.

After doing more of my own research and watching their behaviors, I went out and brought some internal parasite medicine. Put it in Saturday night, and 3 of the 4 angels are now eating fully, the 4th is picking at food but at least he's eating something. My pleco is back to his normal happy self, feasting on veggies.
My plants are also looking alot healthier since putting the new gravel in, so hopefully they will grow now too.
