I've noticed several threads in which people describe their sick betta wedging his/her head under a rock. These bettas seem to be the ones that don't make it. I had this happen with my first betta, Indigo. I think now that it may have been caused by soap in the water, as I didn't know not to use soap to clean back then
, but I can't be sure that's what caused it.
Now I'm curious. Who has had this happen to them? Does anyone know what causes this behavior? Has anyone ever had a betta do this and then recover? If so, how did you save them?
