Advice:Make sure when your buying lighting for your aquarium you pay attention to the details regarding the specifications of the light. I bought a 9W led light for a 10gallon and had to buy a separate light fixture to boost the lighting in the tank.
Advice:Cycle your tank for a good two weeks before adding fish. I lost two out of three fish after one week thinking the fish would help cycle it. nope. Also I didn't know natural sea shells through off my chemical balance in the water too. I took them out the next day.
