female bettas dying

[seffieuk]

yesterday one of my girls died. no signs of anything on her, so thought maybe she was just old...............today, another girl dead (my favourite).........just taken two more out of the tank looking very lethargic.......have tested water, all params ok, all at 0 except nitrate which is about 0.6...........have turned my tank blue with medications but the rest of the girls are looking lethargic as well..............what is strange is that my ottos and corys are swimming around like there is nothing wrong..........is there something that only attacks bettas...........i really think i am going to lose them all.............please someone help. i'm feeling really upset at the moment, this is my first loss...................

noticed their poo? is it stringy and white or a pinkish color? Any laboured breathing? Any lethargy or difficulty swimming? Sounds like an internal parasite or bacteria. Which type I'd be the last to know unfortunately

What do you feed the fish, plus do they look bloated, and what does it look like when the fish goes to the toilet.

Just remember guys that bettas breathe through their labarinths.
