Dagon isn't feeling well =(

A few days ago, while watching him swim around his tank, I noticed a little tear at the end of Dagon's tail. I was a little mystefied as to how he came to injur himself, as there are no other fishes in the the tank, nor any sharp objects for him to cut himself open, nor any trap areas of any kind.

I dismissed the tear and thought that it would heal by time, since there didn't seem to be any kind of infection surrounding it, not to mention Dagon was as vigorous as ever, swimming and digging all over the tank.

Two days ago, I noticed that his other tail was torn as well. Infact, his tail was really frayed, and there were red spots on the end!

I quickly googled the symptoms, and it turns out that Dagon has a bacterial infection called Tail Rot or Fin Rot, where his tail and fins are slowly being eaten away by bacteria. One of the causes of Tail Rot is a sudden harsh change in temperature, be it hot or cold. Well, there has been an incredibly cold front in Oman recently, and that was about the time I noticed the first tear in Dagon's tail.

Tail Rot can easily be treated using a special water treatment medicine. I finally managed to find the right medicine today (petshops in Oman are mysteriously under stocked), took out 50% of his tank's water, replaced it with fresh clean water and added the medicine.

The medicine colored the tank's water a BRIGHT GREEN! It looks so cool lol. And Dagon is swimming around the tank more and also digging again! I hope he'll recover soon inshallah =) The Medicine doesn't affect the other inhabitants of the tank (Bean, the water turtle, in this case) but it could have a negative effect on my plants =(
