I plan on going to a garden nursery tomorrow and they sell really inexpensive succulents. I was wondering if I clean the roots off really well and wash the plants if I could put them in my fish tank. If it's going to kill the succulents or harm my tank I won't put them in my tank. I will also be sure to ask if they use insecticide or other chemicals on the plants so I don't harm the fish. Do you think this would work?
