Sick or dying Betta?

I have a female betta in a community tank. She was never a big swimmer, kind of a lazy fish. I have had her about 5-6 weeks. For the past 3 days she has been laying in her floating log with almost no movement. I keep checking to see if she is dead. About once a day she will take a swim around the tank & then back to the log. I don’t know what is wrong with her. She won’t eat or move. She is not bloated or sinking or floating. She just lays on her side with her head sticking up. She will also lay on the bottom.

Here are tank specs:
36 gal bow front
PH is 8.1, Amonia 0, nitrite 0, nitrate 5
2 female swords
5 female platy
2 male platy
2 female molly
2 guppies
1 female Betta
2 female molly fry in breeder cup

 

Thanks for the info. Yesterday I worked a double so didn't get to do much with the fish. So I think the problem is 1 of 2 things. 1. I think I was feeding her too much. I usually don't do that if anything I under feed my fish but when I got this betta she wouldn't eat. She absolutely won't eat the pellets, I tried the betta flakes and the only thing she would eat is the freeze dried bloodworms. I feed the tank the tropical flakes and she won't eat that either. So in my effort to make sure she didn't starve I think I was over feeding her. The other option is that I DID have a bully but I am not sure she was bullying my betta. I was watching the tank (the same day my betta was "sick" and this new very large Molly fish was chasing my littlest guppy to the point I thought the guppy would die. It was awful to watch so I caught the guppy and put it in my breeder cup with my 2 fry (quite big). The guppy finally recovered after 24 hours and I got rid of the Molly fish. When I returned the guppy to the tank it did recover but that is when the betta was not moving & just laying in her log. So, the Molly has been gone for 2-3 days and I didn't feed the betta for the past 3 days. Yesterday she was swimming around like normal again. She is still super lazy but is acting normal.

Now, yesterday when I was checking the fish I noticed my 2 black molly fish have ick! So, I didn't do the water change as Colin suggested because I took the carbon out of the filter & started treating the ick. I use a product called Ich attack. I also added some aquarium salt & slowly turned the heat up to 89 F.

Any suggestions now?? I did find a dead platy this morning but she is fairly new (maybe 2 weeks) and they seems to be the timeframe my new fish die (if they are going to die).

We do have hard water here.

Thanks!

 

Thanks. I will reduce temp and continue meds for the next week. Once meds are done how much water change should I do?

Also, big question, what can I feed my betta?? Can she live on bloodworms? She won't seem to eat much else. I have not given her food for 3 days. Should I feed her tomorrow?

Thanks!

 

The treatment does not require any water changes during treatment. It says to change at least 20% after treatment. The black mollies I have are newer (1 is about 4 days old & the other about 2 weeks). Whenever I have black mollies it looks like they have ich. No other fish have the spots but then I wonder if it is just their coloring under my white led lights. It appears they have lots of white spots but then when I look closely they just look like part of the fish. Anyone have this experience?

Also, on my betta she is still laying in the log. I will try to attach photos & a video.

 

I have not tried that. Can I get at local pet store?

I am not sure how to upload my videos but did the pics. As you can see her in the log she lays with he head up. Maybe that is normal, I am not sure.
