This morning all my Ramirezi died within 5 minutes. They fell into spasms, their bodies bent, and started swimming spirals through the tank for a couple of secondes, then sank to the bottom, upside down. Any insights? Martin PS: Sorry, I didn't introduce myself. I am new to the list. My name is Martin from Darmstadt, Germany. I used to have Ramirezi, and I still have A. borelli and two specimen I cannot name. I am worried right now that I am doing something majorly wrong. I am relatively novice with dwarf cichlids, I had mine for about 7 months. - -*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*- Martin Rausch Dept.
