Sorry this may be a little long, the problem has quite the story behind it. I am new to fish and I got my first fish tank. I currently have a 10 gallon tank. I have had it for about 2 and a half weeks. I made a stupid choice by not doing the nitrogen cycle, I did not know about it at the time I got the tank.
I got 4 goldfish. Yes I know there to small for that size tank. I got them so I could get the tank started and see what happened. The first week was fine and my test strips had nothing out of the norm. So I decided to get 4 melini cory catfish to go along with my goldfish. I cleaned the tank the next day and I noticed that one of my goldfish had these black marks on it, which I immediately thought were ammonia burns. If that what is was I don't know, so I decided to go get the API Master test and I tested the water the next day. The measurements for both nitrite and ammonia are the strongest the color can go. So I quickly put some ammo lock in. I did some research and it sounds like I have New Tank Syndrome. Does this sound right? I thought to myself that I need to get these goldfish out because they are producing to much, so I put them in my pond. I am doing every other day water changes and putting in API quick start each time, obviously I put in Tetra Aqua safe to dechloranate the water. The nitrate went to a safe level but the Nitrite and Ammonia are still of the charts. I think that my cory catfish are feeling it because they don't eat and just lay at the bottom and SOMETIMES move.
I don't know if this is normal or not. I don't know what else to do. I will do anything to keep those fish alive in that tank. Any ideas how to keep the levels down. Also I think its way to early to for the fish-in nitrogen cycle for these levels of ammonia and nitrite to be peaking, but I could be wrong. Once again any ideas on what might big going wrong would be greatly appreciated. Also sorry for the long message. I just don't want my fish to die.
