I got Hamish about 6 months ago. He is in a 1 gallon tank. There is no heater, but the house is always kept very warm. There is no filter and I do a 25-50% water change each week.
He has always been happy and an extremely lively little guy. In late November he stopped eating for about 2 weeks and his abdomen became extremely swollen. One day his right side (just behind his fin) literally exploded! It was a huge open wound and it looked like his intestines were hanging out!! I added epsom salts as per my pet store advised. Eventually the mass fell off and he was left with a large gaping wound. It looked like something had taken a bite right out of his body. At this point I also started adding some drops to help heal damaged fins and scales.
He remained hidden in his cave for several weeks, rarely eating....I thought he was going to die, but his side slowly started to heal!
The last week or so he has been his old energetic self and eating regularly! I was soooo happy! He swam with a bit of a wobble due to his previous injury, but he was almost as good as new!
Just tonight I noticed a small protrusion where his wound used to be and a small pink string hanging out (almost like poop).
Please help me!! I hate to think he is suffering!!
Is it his food? I feed him betta pellets. He has always refused to eat blood worms.
