Fiona died to an unknown cause, here the story,
The Dead Fish
One day i was waking up and i fed Ritotini, Sakai and Betta Max. (Betta Max Is my brothers fish.) and Ritotini and fiona where in my spawning tank. I noticed she didnt come out for food, then i realized bettas can go for a while without food, or maybe shes bloated and doesnt want Ritotini to see. (lol.) so i walk past, and get dressed, get my backpack and go to school.(i ate breakfast already.) so a couple days later i was worried, i lifted up this cave like hidey hole and found her dead, she floated to the top, i still miss her dearly, and i dont know how she died so, i feel like its something that i did.
