Cool Cycling 20 gallon tank with 8 Serpae Tetras (79 Degrees)

Im just wondering if things are going well and if my tank is overstocked or not.
Marine-Land filter with BIO-Wheel for up to 50 gallon.
PH- 6.9
Low Alk

I've been Cycling for almost 3 weeks this is my 3rd weed. The first week I had 4 goldfish during that first week i added 6 Serpae Tetras and got rid of the goldfish. A couple of days later I added 2 more Serpae Tetras. Now during the second week I noticed Ammonia levels staying at 0 and Nitrites staying pretty high at 2.0 ~ pmm it would get down to 1.5 ~ ppm when I would clean it for the most part it stays high. It's the 3rd week and nitrite is slowly rising Nitrate is pretty low but also rising. Does this sound right?

I feed them high quality flake food usually, Twice a day. Sometimes I throw in some Micro wafers or bloodworms instead of flake.
I do a 20-30% water change every 3 days.

Your cycle looks like it's going good. In the future you should look into doing a fishless cycle, that way no fish are getting poisoned from the cyling process.

With 8 Serpae tetra I would say you're pretty much stocked. They can be fin nippers so I wouldn't want to put anything else.

I have a 20g tall with Serpae Tetra also, that's all you'll be able to do since yes, they are nippers.

You could maybe add cory's, maybe 4 but they do like higher numbers. I have 6 tetras and 4 corys in mine with lots of plants. Don't add them though until the cycle is complete.

No, substrate fish are usually left alone. The tetras completely ignore them in my tank.
