i have 3 upside down cat fish and 7 neons. they were in my 20 gallon tank for months i added 8 rummynose tetras and they have been dying. my other fish look fine but the rummynose look white and never got there red head back. my ph is 6.7 ammonia and nitrites test o can anyone help- before all my 8 die. so far 4 are dead.

Tetras are somewhat weak fish. It might be that they weren't handled properly before you got them.

Do you know what your NitrAtes are? As entioned above rummy noses are weak fish and perhaps you hae higher nitrAtes than they can handle.

That is too large amount of fish to add to a tank at one time. It does not give you biological filtration time to catch up. Adding more than a few fish at a time to a tank of your size stresses out the current inhabitants and the newbies. Not to be a nag here, but I had the same problem due to being a little excited. Be patient and make the experience last a while.
