A terrible day has occured.
Over the past week, I went to Joshua Tree. I left my most trusted friend and gave him specific instructions. He fed the tetras around 2 TABLESPOONS of flakes TWICE A DAY. My fault for trusting him, but I still showed him 2 times. Anyway, he put too much, and when I came home, the bottom was riddled with flakes. I do an immediate water change of 85%. Test ammonia - .25 ppm -. Oh crap! The ammonia probably converted to Nitrite. Nitrite: around 2 ppm. 4 80% water changes later, my prized male floated around, and I could touch him, and he would flinch only, not swim away. He is breathing rapidly, la-dee-da, we know it is Nitrite Poisoning. I go to bed at 2 in the morning because I did water changes with a two-hour period in between. As I am going to sleep, 2 other big ones start to act the same way. Now I am freaked. I tell my dad that there is little chance they survive. I didnt have aquarium salt. I posted asking for help, but there was nothing I could do. I had iodized table salt, and other salts that wouldn't work. I go to bed.
I wake up in the morning. I run to the tank. Every Tetra is breathing heavily. I look around for the big tetra. He isn't there. I finally find him in the barrels unmoving. He was dead. I pull him out. I realized this: He is THE PRETTIEST Congo Tetra I have seen ANYWHERE, even on google. I mourned him for over an hour. I was planning on posting him for the POTM. I go to school; my face red from tears. I was so attached to that fish. He used to eat out of my hands, and jump out of the water when I held food above. I buried him in my fish grave outside. After school, I got API Aquarium Salt, and dosed the tank according to Rocksor's suggestion. I turn the heat down to 76 degrees. As I am writing this, everything is fine. I will gather some pics of him to commemorate the one and only Buddy, the best (in color, and in swagger) Congo Tetra ever to walk the fish tank.
