I acquired two bettas (male, crowntail) this afternoon and am already absolutely in love with them
However, I've noticed one of my bettas' gills are always flared out. Being new to bettas, I first thought it was because of low oxygen levels or it was part of his display as he was very fiery and aggressive at the store but now I see it probably indicates a health problem.
-Both gills are flared symmetrically
-No visible fungus, open sores, tumors, ect.
-Gills are always flared out completely (I can see all the way into them from behind)
-It's hard to tell if the gills are red from inflammation since he is a mottled red and peach color
-The "frilly" tissue under the gills is always flared out
-Heavily flaps his gills
-Sudden dashes to the surface to take BIG gulps of air
He's still VERY active
and VERY curious
. I don't see any fungus or parasite-like things on his body. It's very possible it could be from ammonia burns as he was in a very small amount of water at Wal-Mart but I can't say for sure. I've lowered the water level so he can swim to the surface easier.
Could it be ammonia burns/scarring, or a bacteria/parasite/something contagious?
I'd like to know as my tank is split in two with a divider, so the two fish will be sharing the same body of water and I don't want it to spread from one fish to the other.
I'd really appreciate any input on this. Thanks in advance!
