Caring for a disabled fish in a very small tank, or letting it die?
I know this might sound like a really stupid question, but... a breeder ended up with some deformed Ramirezi fry (they shared a video of them); the fish have no fins. The breeder is trying to decide whether or not to let them die. Personally, I would never do that, since the only issue is the lack of fins. Anyway, I’m wondering: if the breeder decides to cull them, could I take just one and keep it by itself in my small, heavily planted 15-liter tank? Or would it be better for it to just die? I realize how small that tank is, but... well, it’s the best I can do.
TLDR: The breeder is trying to decide whether or not to use the fish as feed. Should I let a breeder's disabled Ramirezi fish die, or would it prefer to live in a 15-liter tank?
