So this happend to my previous rosy tetra, rapid breathing otherwise no other symptoms. Happily swimming eating until after a week. Then he died but was bloated and had eyes bulging. I attempted to treat him with a dewormer and salt as recommended by a friend. I increased oxygen with an air stone but doubt it was oxygen deficient as my aqaurium is heavily planted and understocked. For safety I dewormed my entire aquarium.
After he died there was no other fish with these symptoms. Now I have another beginning to breath rapidly and I'm worried the same may happen to this guy...
Any ideas what this is or what I can do??
