Help! Spinning betta

[LiveMermaid07]

Perhaps a week or 2ish ago I noticed that one of my betta girls - Nadette, roughly one year old I think - was swimming a bit 'tilted'.

This morning I found her and she's completely tilted over on one side and can only spin in circles when she tries to swim. :help:

Since she was having trouble getting to the surface I moved her from the 29g to a 1g and tried to set some decor so she could rest on it near the surface.

After moving her I noticed that on one side she has a slight bulge past her middle.

Any idea what's going on??? And how I can help her??
Please help!
She's been getting worse all morning, I'm afraid I'm gonna lose her! :cry:

I've had probably close to 100 Bettas (male and female) over the years and 90% of them die with a lump on their side after a few yrs. I don't know if Bettas nowadays are prone to tumors or what the deal is. I've always kept them in tanks over 10 g with filters and heaters and fed them properly, always changed their water weekly. I don't feel it's been lack of care & I'm sure in your Bettas case it's not lack of care either.

tumor? Oh my..

Could it be swim bladder disorder?

Maybe. From the pics I saw she's not swollen in the correct place for sb, but some of the symptoms sounded right on. I figured even if it was a tumor, the 'cure' for sb didn't sound like it would hurt her, so I tried that. She does seem to be getting somewhat better. She's not spiraling anymore anyway.

But now her head is smaller... ??:uhoh:
