New fish....have a question

High Nitrites! Please help!

Hi everyone
I have a question about my 29g tank. It has been set up for about 2 months now and has 2 clown fish, 1 spotted shrimp goby and 5 turbo snails. I just added two Banggai cardinals 2 days ago and tested my water today. The Nitrites and Nitrates have gone up a little bit. Will the fish be ok? Is there anything I can do to help get the levels back down? Thanks
PS Also, I don't know if my Banggai's are eating. they just bite at the food and spit it out. I am feeding frozen thawed blood worms and brine shrimp.

My Nitrites are still high and I can't find any information on how to lower them or when to start worrying about them. Any info would be helpful. :huh:

What is the ammonia level? Most likely, what you are seeing is a mini-cycle that will result every time you increase the bio-load--the increased waste from the additional fish overwhelms the existing bacteria colonies and they have to expand to consume it all. This takes a few days. If the levels spike significantly, you should perform water changes as needed to control the levels.

You might want to try a more varied food--that's pretty high protien.

my ammonia is at .25 but my Nitrites are at .50!!!!! I just checked them tonight. Is that going to harm my fish?? Please help!
