Congratulations "litlpnoi," you have just murdered some poor innocent fish that were depending on you for their lives. You flushed them down some tubes to suffocate and die in your sh*t. That disgusts me that you could possibly be so ignorant and stupid. How the H*ll are you catching fish without a net??? With your hands? How old are you? 5? You are far too immature to have any living creature. You also wasted your money on your fish tank set up, you can easily buy a brand new start up tank kit for $40 at any fish store.
How would you like to have been flushed down a toilet? Think about it.
And before you go doing anything else stupid, it's too late to fishlessly cycle your tank, so don't go out and buy ammonia and add it to your tank. Do some 25% water changes daily and let the remaining "lucky" goldfish cycle it for you. Regularly take your water to the fish store to get it tested for ammonia and nitrites, or buy the tests and do it yourself. Once the tank is cycled, take the goldfish back to the store for store credit and get some fish that you feel are worth "nurturing." Idiot.
