My Greta is not eating anymore. She stopped eating her cichlid food over a year ago and would only eat live food. Now she isn't even eating that. She hasn't eaten for a couple of months now and all she does is hide behind the driftwood in her little cave. She's over 13 years old now and I'm afraid she's dying. :'( Any advice for me? Should I be finding a way to humanely euthanize her? If so, I don't know how to do it. Here's a picture of her in better times:
