I would like to seek for the advice on what kind of gravel and substrate should be used for a golden fish aquarium. My purpose is to establish a good and stable environment for both golden fishes and plants, and the plants which I'm going to select are Java Fern and anubias nana. The size of my golden fishes is 2-3 inches long. Is the usage of substrate which targets for plant is necessary ?


Pls advise me.

Thanks.

Java fern and anubias don't require any substrate at all, you can just attach them to rocks and wood, and feed them with liquid fertilizers. So you can choose any type of gravel you like, preferably a neutral one (that doesn't increase pH and hardness) or even leave the tank without any gravel (bare bottom) if you prefer.

To keep goldfish and these plants together, your goal should be a pH around 7.0-7.2. Keep in mind that even though these two plant species are hardy, the goldfish may still damage them...

I have approximately 10kg of GEOsystem fine black gravel (#12649) in my tank, as I required something sand-like for my dojo loaches to be able to burrow in without damaging their barbells. It's by far my favorite aquarium decoration.

While GEOsystem claims this particular gravel won't increase the alkalinity (KH), it will actually spike up for about the first month or so, then it will come back down, depending on the frequency of your water changes. Expect the GH to rise, too.
