Bubble Eye Goldfish

I just recently bought my brother a bubble eye goldfish. The plant that I thought wasn't that rough punctured one of the sacs. She's in her own tank with little current. I have removed all of the decorations and left a bare bottom. I've put a lifeguard all-in-one treatment tablet in today and will continue treatment for the next 5 days. Do I just leave the inflated sac hang on her or should it be removed in some way?

 

Just keep the sac as it is. But maintain the water change regularly.

 

Make sure you keep the water clean and she should be okay.

 

I'm doing a 25% water change everyday. She has an air stone in there as well and I'm cleaning her waste from the bare bottom every day.. Should I be doing a bigger water change?

What size is your tank? I'm assuming it's cycled. Is this true?
