Hi all! One of my ember tetras has this white bulge on the side. She's quite bloated too but it looks like it's because she's pregnant (a couple of others look like that too sometimes). She's active and swimming with the school. She's in a fairly planted 10 gallon with 8 more embers, a female betta, 2 nerites and some amano shrimp.
Water parameters are:
Ammonia: 0
Nitrite: 0
Nitrate: 25
GH: 300
KH: 80
PH: 7.4
No new additions in about 6 months and temperature is a steady 78°
Any ideas what it could be?
