There is Neon tetra, too. I was going to let GHD swim to a Corydoras water tank together.
However, I stopped it because I let GHD die of an illness in the past.
The waterweed which I can plant is limited. This is because it uses “bottom Sandoz” which is not “soil”.
I am going to make waterscape comprised of driftwood and a Microsorium.
I bought Echinodorus for these water tanks last month. However, “difficult problem” happened and set it to other water tanks.
The photograph of the water tank is this.
I want to increase fish a little more.
