I took my first vacation in 3 years to Arizona over the weekend. I asked my fish keeping buddy to man the fort while I was out. All of my fish are fine, except for my cichla grow out tank... Ammonia was through the roof, and my Azul, Xingu, and two Orinos kicked the bucket... I don't need explanations. I'm just venting out of shock. I'm seriously considering just leaving the hobby. I get too attached to my fish so I don't handle these things well...
