heres my suggestion, bring your fish back to the store. clean out your tank, start over, do not put any fish in the tank untill you understand what a cycle is, and do a bit of reading. if your not commited to properly taking care of a pet, then maybe you should not have them, its really not that much work, or responsiblitity having only 1 10 gallon tank, and if you dont have the time to do it properly then you dont need to have them at all. no need to make any creature suffer because you dont do your research or proper care. I know how hard it is when your young to try to find time for it but if you are commited to keeping pets of anykind then you need to make sure you are doing whats best for them. i have 4 dogs, 1 cat, 5 tanks and 2 kids, and i still make time to take care of them all and have time for myself.
