Why does my fish water smell?

Question

It is not a very strong odour and can only be smelled from up close. Is this a problem for the fish or just something that happens. Hard to explain the smell its a bit unfresh I would say.
I only have 2 goldfish in quite a large tank. Can't remember the exact size but I ensured it was big enough when I bought it.

Answer 1

Remember that your tank is also a breeding ground for several types of bacteria that provide a safe environment for the fish. It's virtually impossible to have an aquarium that's both odorless and healthy. However, there are some smells that can be removed, which have to do with waste and feeding.



Some aquarists like to feed their fish egg yolk every now and then as a treat to fish. However, overfeeding them with this gives the aquarium a serious smell.



Dead fish cause raised levels of ammonia in a fish tank. If you have recently lost a fish, you should do a 25-50% water change.



Plants can cause smell too, make sure none of your plants are dead, and that there are no leaves floating around.



Overfeeding causes waste to build up in the aquarium and it's filter, and can also cause smells. If your goldfish have long trails of feces, hanging from their rears, they are probably being overfed.



Still, I wouldn't worry too much. Like i said, an odorless aquarium is probably an unhealthy one

Answer 2

It's because your water needs to be changed. It's probably stagnated and the food your fish eat is made from dead coy and the food makes the tank pretty discusting. Get a snail to clean the mess up. How ever do not get a bottom feeder because goldfish release a toxin poisioness to other species of fish.

Answer 3

Large(50%) weekly water changes-with a dechlor product added. If you have substrate, gravel vac it often also. Goldies are extremely messy fish

A healthy fish tank does not smell, at least not badly. Slightly musty like Dallas mentioned, or "peaty" is a healthy smell for a fish tank.

A faint smell when you stick your nose in is normal. It should smell "earthy", like dirt or damp leaves under some trees, a sort of "natural" smell. There are bacteria, algae and other micro-organisms living in there so it's a little ecosystem with all sorts of organic stuff going on and it will have some smell.



If it stinks like dead fish, then you have a problem.
