Not Sure I Wanted To That.....

so i know i have a deep substrate and have decided i soon want to replace te gravel with a sand subtrate. i have been slowly cleaning and removing gravel fo last week or so...

tonighti scooped out a few kg worth from some of the deepest parts, when i did so there was rather a lot of gas bubbles went dancing merilly to the surface - am concerned i hve disturbed some anerobic gas bubbles, is it likely to have harmed the fish?
i have done a water change and am nervously watching the fish - they all seem ok at the moment

should i worry?

Some trapped gas is fine, if the gravel was black and the gas smelled really strong then it might be sulphur dioxide, smells like rotten egg. I have had it in the past with no problems for the fish, that I could see. I wouldn’t be worried, you can keep an eye on the fish and do another water change if there is any cause for concern, but I doubt there will be.

Yup if you aren't smelling that awful rotten egg smell so bad you have to throw up then you are fine.

Do you have malaysian trumpet snails? They leave bubbles under the gravel too.

Hence the name "trumpet", I suppose?
