In Memoriam
So I've noticed that my yuma has a huge hole in the center of it, what possible suspects could have done this?
Nothing ate it, it had a bacterial infection a with most yumas that die like that. I have had many do that some with in weeks of acclimation. That is the number 1 cause of death with them. I starts out infecting the inside and eats a hole in the base right under the mouth of the polyp. Was there clear slime? That polyp looks like it has been infected for quite some time due to all the necrosis of the tissue and damage. I would remove it so you don't pollute the tank.
The protozoans is different animal all together John and from what I have experienced do not infect yumas...
