SIP little fish!
I feel so sad when I see posts in this section...I'm so sorry for your loss.
So many people losing their little fish friends, and I've never really experienced that fishy loss myself, so I can only imagine! I guess I've just been lucky, as all of my bettas have come from pet stores...it scares me to think that I could lose one at the drop of a hat with no explanation.
Again, I'm sorry for your loss! At least he got to feel love and cared for before he passed, I'm sure you did everything you could to make his last few days wonderful.
