dont know why it died.? i swear i have spent like 0 on fish because they keep dying ! I have the heater thing and the filter. everytime i get a new fish they day like a day or two later. and the fish tank is always clean so i dont know what the heck is going on. I clean it once a week and feed them once a day... does that sound right ? If not correct me please. I use AquaSafe water conditioner. and everytime i change the 25% of the water i put in a little bit on the water conditioner in the tank... thats pretty much what i do..

Help me ! lol.
