Lucky but also Unlucky
It seems all the plants in my 12g do amazing but as soon as I put a plant into my 2.4 the plant dies. I treat both with tetra plantamin and the temps are 80 degrees. I recently put a fountain plant from my 12g that was doing fantastic, into my 2.4, I love this plant and today I have noticed that some leaves have turned from a vivid green to a dull brown. The only thing I can think of is that I only put a light into the smaller tank last night but I also thought the greener the plant the less light it needs. Is there a way I can salvage these plants? they arent totally dead just certain leaves are slightly discoloured

In an aquarium the effect of relatively minor changes can often be significant because you are working in a relatively (compared to nature) small closed system. Changing the type of light can cause some plants to react either negatively or positively.

I would leave the plant, ensure it has good light (which you now appear to have done) and receives nutrients (your ferts), and it will likely rebound. Remove brown leaves, they will not recover. If new growth is evident, the plant will; if this is the common Fountain Plant, Ophiopogon japonicus, it is quite hardy. This even though it is not a true aquatic plant but one that usually adapts well submersed.

Are there any plants that require little to no lighting?

The designations "low light", "moderate light" and "high light" are somewhat subjective, since most aquarium plants will grow fine in what many would consider "low" light but what I call "normal". There is no guide to this, as tank size, type of light and nutrient availablility (from fish, foods and fertilizers) all affect things too.

Could indicate the light you have and the tank size?
