Hey everyone,
My brother has a male crowntail Betta. For the past few weeks, heās been sitting on the substrate all day. He doesnāt swim up to eat and doesnāt interact with us anymore. Initially, we thought it was boredom so we upgraded from a 3 gallon to a 5 gallon tank. This didnāt fix the problem and we noticed that one of his dorsal fins was torn off. I made sure that our water was clean and itās starting to grow back. He still lays on the substrate and has started to grow a weird lump under his gills. Does anyone know what the problem is?
Water test results:
Ammonia: 0
Nitrite: 0
Nitrate: 20 ppm
pH: 7.5-7.7
I attached a picture of the lump.
