i dont have any fish in my tank

is this bad about 3 weeks ago i was selling my clownfish and the guy wanted to buy my fire fish also so why not i wanted to get something different and i dont have lots of room in the tank so i let him buy them all i do have a cleaner shrimp 1 large turbo 4 hermets 1 under the sand snail (cant remember the name) and 3 smaller snails i got from petco not sure what kind but thay eat algae. what im wondering is not having any fish leaving something out that will throw off the balance in my tank.
thanks for the help!

 

It won't throw anything off balance as long as you put a little food in the tank. I believe you are thinking of nassarius snail.

 

yea thats it thanks
