Hello everyone!
My ryukin lives in a 20 gallon long that is filtered and aerated, cycled, temp at 80F in summer months. I test the water every 2 days and everything looks pretty good- Ammonia: 0 Nitrites: 0 Nitrates: 10ppm. She eats very well, loves attention from her humans, and is constantly exploring.
The only thing thats off is she seems to "faint" a lot. She'll be swimming along and then slow down and will stop moving her fins or body, just sort of float there for a few seconds. Then she takes off again and so on.
She doesnt have any other signs of illness- everything is normal. What do you think could be wrong with her?
Thanks so much!!
