Planted tanks and gravel are usually not recommended for Gold Fish. However, I have had a planted gold fish tank with Vallisneria, Java Fern and Onion plants for almost 18 months now. The substrate is 2" of gravel.
Here is my question. Can I convert this entirely into a planted tank with SOIL and gravel substrate. My gold fish do dig the gravel and sometimes have even choked on it. Luckily I caught them in the process in time. Now, if I add soil, can the gold fish eat the soil after digging the gravel ? How is this problem solved in nature. I am sure there must be soil in fresh water Gold Fish habitats.
Thanks.
