Crude caveman drawing of 55 gallon tank idea. I would love thoughts and opinions on stocking ideas and would love some input on plants to use. The Gouramis are Blue Gouramis, Male and female pair. It also has a Fluval 305 filter. Anything else I should be getting? I know I don’t need air stones for the Gouramis are Labyrinth fish and prefer a calmer surface. This is my first “big” aquarium and I am super excited about it but I want to do it right. Was planning on sand, soil, and gravel substrate in that order bottom to top. Also, could use input on that.
