did u let the tank cycle? Smelly water is ussually a sign of high ammonia

First off, you need to know about the nitrogen cycle in aquariums. Read the article below, it's good to inform you about how it works.

I don't know what could be causing the smell, maybe someone else can help you with that.

It could be decaying food within the gravel. How often are you testing your water? And when was the last time you did a water change with a vacuuming of your gravel?

Smelly water usually has a film on the surface. The water smells because of high ammonia. The tank has to cycle before you put the fish in. If you put the fish in a tank with new water and new filters it will take a while for the ammonia to go away. In the mean time do 20% water changes once a week and try to keep feeding to a minimum since decaying material and fish waste cause ammonia build up. Again be sure to keep up with those water changes because after the ammonia goes away you will have a nitrite spike and a nitrate spike and this is very stressful on the fish and could cause death.
