My fish aquarium smells bad! I have a five gallon aquarium and a betta fish. He seems happy and normal. I just recently moved him from a one gallon into a filtered and airstoned place. The water is clearish but not as clear as i would like it to be. Anyway, back to the smell. My tank has a full cover on it and when i open the cover it smells like carbon or sulfer or something (not like clean water). I have a thermometer on the tank and it says its between 78- and 80-degrees. I am a total newby at all of this stuff so I am not even sure if the smell is normal or not?? All i know is that it is really strong like knock you down smell. Can anyone help? I dont have a water quality test kit cant afford one right now either.

Tank water should not smell bad. Perhaps a little organic but certainly not bad.

How often are you doing water changes (per week and % amount?)

Is the tank cycled?

Do you have a filter?

Is your betta acting well?

What water conditioner do you use?

I need some more information in order to help you.

I have only had this tank for a week and a half. I have done a 25% water change. I am not sure if the tank has "cycled" yet becasue i dont know what that actually means. Yes, I have a filter and I am using Tetra Beta Safe Water Conditioner. My betta is acting like normal, swiming up and down and around things ... Not toooo active though just a normal swim-y pace lol

Okay if the tank is not cycled you need to be taking out 25% of the water every other day. In your case about a gallon.

Since it has been a while I would do a 50% water change today. Match the temperature of the water within one degree of the temperature of your tank water any time you add water to your tank. Rapid changes in temperature are stressful to fish. Then start 25% every 2-3 days for three to four weeks.

If you can get hold of a water testing kit (the best is API master freshwater testing kit) then you would change water anytime ammonia or nitrite get to 0.25ppm. This is more exact and you may have to do less water changes and therefor cycle your tank faster.


Fish continually produce ammonia. Ammonia at any level is toxic to fish. A cycled tank has several kinds of bacteria that feed on ammonia (and the resultant nitrite) and convert it to a non toxic substance called nitrate. You keep nitrate low through weekly water changes. But it takes time to develop these bacteria and until you do you need to keep ammonia low by changing the water.

Here is a great simple explanation

I think you will find if you start changing the water more frequently your betta will be happier and your water will not longer smell.

The sulpher smell is sometimes cause by something called anerobic bacteria.. Gunk gets caught at the very bottom of gravel,especially with deep gravel.. Sometimes when u do a water change it can disturb the pocket of gas this forms and release it into the tank.. I lost a fee fishies because of it,mine was bad tho..established tank that needed a gravel clean sooner really.. I believe lack of oxygen in the water can cause the same thing.. Either way an air stone is what helped mine out.. Water changes did nothig so i put an air stone under the gravel at the back and next day smell was gone,fish were happy.. If water changes dont work try a very low lowered air pump with a small air stone,very small so only a few bubbles just enough to move the water slightly but not too much as bettas dont like fast movement..

it might be because you are over feeding the fish that is what a pet store owner said to me,

90% of pet store employees are morons and have no clue

In a small tank like hers, a simple plant will absorb most of the pollutant, a carbon filter would also work as cleaning the water and clearing up the smell, a small one for your tank would be like 15-20 bucks
