How to match fish in a grass tank?

The bottom layer of the aquascape tank is usually sand White gravel Then there can be some rocks with holes in them, or you can use submarine wood, and then mainly aquatic plants.

Sand and gravel bottom layer, wood can be made into a small bridge, or rockery, wood can be tied to some moss, short aquatic plants can be placed against the center, high aquatic plants to do the background, usually like to have a grass tank of friends like to set up the tank into an ecological pool of water, but I like to set up like a forest. Wish you success! It takes some thought you will find it interesting. Then I will give you a suggestion, 1. Don't let the temperature be too high, or the water plants will grow like crazy, beyond the water surface, it's hard to fix it. 2. That is, eliminate the snails immediately when you find them, it eats grass, and it will also reproduce in large quantities, don't think it's cute or ecological just leave it, otherwise it will be miserable. The above is my personal experience, all hand-typed.
