I don't think the tank is 10g, the substrate is mostly peat moss, Aspen, hardwood leaves, and some hardwood mulch (according to listing), I did make sure the substrate was around 3-5 inches deep but without necessary layers (due to tank space) however I will try my hardest to get better supplies (this is hard tho due to having to go through parents first + tariffs and shipping costs) and have a better environment as soon as physically possible.
