At friday everything was fine, didnt seen him till saturday night.
At saturday night he was lying in agony. The first thing I've seen was he has been lying on his same side always.
I removed him from my divided tank immediatly did %100 water change added aquarium salt and vitamin complex to his jar.
After few minutes, I took him out from his jar for closer look and I realized that scar is bilater and symmetric.
Here are the pix of him.
Housing - 3 gallon
Temp - 77 F -25 C (constant with heater)
Weekly %70 - %80 water changes
Food - NLS, Attison Pro, Attison Betta food
Could it be TB? If yes, I'm freaking to death now, I had a scar in my hand when I changed his water 2 days ago.
What could it be? Should I worry about my other boy?
