Hi Andrew and welcome to the hobby.

You should probably hold off on anymore livestock and let your tank cycle completely. Cycling a tank can take some time(In my opinion the hardest part of all) wait until your water parameters are stable. I would suggest going to a local fish store and buy yourself these test kits: Ammonia, Nitrite and Nitrate to start with. Start with ammonia to see if the cycle has started when ammonia start to drop test for nitrites when nitrites start dropping test for nitrates when nitrates are 0 then your good to go.

In this hobby you have to take your time in the beginning and read read read.....

I would suggest researching about nano tanks so you can get an idea of you can and can't have in your tank.

Can you give everyone some details about your system (lighting, skimmer, water flow, using tap water or RO/DI).
