Everything in my 55g is dead. Everything. The entire school of tiger barbs, my angelfish, all of the kribs, the snails, even the plants. Yesterday, they were all fine. They were perfectly normal. Today, I went down to the basement to feed the fish and check on everyone, but I didn’t see any movement. I figured they were just still sleeping, as I hadn’t turned the light on yet. When I did, the it was awful. Bodies all over the bottom and piles of brown plants. Not a single ramshorn snail sticking to the glass. My kribs weren’t there to say hello to me like they do every morning. The barbs weren’t begging for food like they always are. They were all pale and dead on the bottom. I checked all levels, and they were normal, but as soon as I checked the temperature, it was ice cold. I read the thermometer, and it said 45F. I don’t know what to do. I’m utterly devastated. I have snails in other tanks, but what about the kribs? I had one solitary angel in there as well, his name was Fettuccine. I loved him so much, he was my little baby. I can’t tell my younger siblings right now, they loved him and the kribs too. I feel like it was my fault for not checking on them earlier. I might’ve been able to save them. I raised those kribs from babies, and I loved them the most of any African cichlid I’ve ever kept. I don’t know what to do. I just hate seeing it empty. I want to wait a while, and I don’t want to feel like I’m replacing them, but at the same time, I can’t bear to see it so lifeless. I’m not going to let the cycle crash, and I’m going to do a full rescape. I don’t know what the stocking will be, but I’ll definitely have kribs. I hate myself right now. I could’ve saved them so easily.
