Hello Ravenmoon! Your baby spider still has a chance to survive, I still see good roots. If you intend to keep them growing in water, you can try using clay rocks. I grow one indoors in clay rocks and water semi-hydro style. So I have a container where I have two holes punched a few inches from the bottom of the container, not below the container. So it is like the spill over hole, when I water the plant from the top, water spills outside the holes and keeps a reservoir below. The plant then just grows the roots deeper, and the clay rocks wicks water too, so it helps keep the roots just adequately moist without making it too mushy. At the same time it allows air around the roots. Those roots are quite drought tolerant as it matures so it likes to just be moist and dry out gradually. I like this style indoors, no pesky gnats.
Or if you want to grow them in soil, it will also work, just do not be surprised if the roots die off a bit, it will be adjusting from water to soil media. But it will also grow the proper roots later on. Use a very well draining media in a small container, the plant is still too young. Keep it warm, in bright light.
