Felix attacked Erin! UPDATE: Post #8 PIC ADDED: Post #9

[BC_MoM]

Tonight I put my male and female back in their divided 20g tank. I always keep an eye on my fishies after a water change to make sure everything is okay. I came back a few hours later and Erin was gone.

I looked into Felix's side, and she was laying on the bottom not moving. At first I thought he'd killed her, but I saw her breathing. I have NO idea how she got over there. There are no gaps between the divider or the tank, no holes in the divider... there is a TINYYY bit of space between the lid and the top of the divider... she may have gotten through there, but I have no idea what would have made her do it.

ANYWAY.

It appears he tore her beautiful tail fin. It used to be perfectly round, and now it's all ripped. What can I do to fix this? Or is it something that will just heal in time?

My poor baby girl... she's hiding under her shell now and won't come out.
