Two and a half months. All sorts of things have grown on it, and been eaten off by my clean up crew, but this is new. It started about two weeks ago. At that point, I had three amano shrimp, two otocilclus catfish, a snail, and my Betta.
Friday before last, I saw one of my huge shrimp eating a dead oto. The shrimp were also shredding my plants! I fished out the dead oto, caught all the shrimp, and went to my LFS, where they rehomed the shrimp, and sold me three new otos.
Here we are a week later, the plants are recovering, but I found another oto dead. 😕
I don't know what, if anything, I am doing wrong. There is plenty for them to eat, and the water parameters are good. It all got squirrelly when the white stuff showed up, and that could be coincidence, but I figured I'd better ask the community.
