So, went back to the store yesterday to see if the CT I wanted was still there, he wasn't :( I hope he got a good home. But...I saw something really disturbing. A King betta, swimming in his cup fine, active....but with a large hole in his head....? Like, a big chunk missing and its all greyish white, it was really gross :(
What is this? Is it something that could potentially be treated/healed/fixed?
I don't think it would, but that's only from my POV. With that much of a wound, the water would have to be constantly changed to keep it clean until the betta's slime coat could cover it (which might explain the greyish white).
You might even end up doing an AQ Salt treatment right when you bring him home in case that white-grey is a fungus and NOT the slime coat.
Really just depends on your dedication for it...and I would go for a minimum of 3 gallons. Maybe 5? I just know that kings require a lot more water than a normal betta x.x
Could be hexamita, known as "hole-in-the-head" once it reaches the external stage. Possible causes are thought to be malnutrition and poor water conditions. If that hole looked pretty bad, that king betta may be too far gone :(
Unfortunately, I've seen it before on an oscar (he wasn't my fish, thank goodness). Prognosis is not good unless it's caught real early on and treated aggressively with strong industrial meds. It's one of those diseases that TLC, some AQ salt and ultra-clean water can't cure. Pretty disgusting and really quite sad, what a way to go...
