The goldfish plant does not have a succulent. In exchange for their beauty, you can give them another plant. However, an iceplant is a better choice as it is simpler to remember and say. Although it is easier (and more healthy) to place your succulent in another pot, properly preparing your container will ensure that your plant has a better chance of survival. You can grow succulents in pots that don't drain, like a cache pot. If you have a drill, you can drill holes into an existing pot. You should use a cactus/succulent mix, which dries faster between waterings than regular potting mixes.
