Okay so about 2 days ago I noticed my cherry barb was a bit fat. I looked closely and made an assumption she must be pregnant (off of a little research off the internet). now 2 days later her gills are red and her scales look like they are not flat =( I feel very badly for her she must be in pain or something but I have no clue what I can do for her. I am strapped on money and please do not go down the road of “then you shouldnt have pets” unexpected things have been coming up and my children come first. I just need some advice on what my poor fish could have and anything I could do to help it. Thanks!
Just an FYI
None of my other fish are sick
My tank has been up and running for 4 months
I have 4 scissor tail fish (one did die when my household was at hospital for 4 days with my newborn =( )
I have 2 other barbs not including my sick one
All my fish school together and are very friendly.
I have a 10 gallon tank
my filter filters 100 gallons an hour.
I change the filter every 2 weeks. (not the biological one, I have never touched tht one)
I have no live plants yet.
I have no amonia
no nitrites
5 nitrates
and PH is 7.0
Just tested yesturday.
