Hey everyone. I'm in a bit of a spot. I have two Blue Candle (Azureus) cacti, Harry and Lloyd. Harry is about 6 or 7 inches tall, and Lloyd was about 3. They shared a pot together until earlier today. Lately, Lloyd's been getting smaller and darker It's now much shorter, thinner, and the needles have gone from a pale yellow to a golden/brownish color. It is also kind of squishy (i noticed when I moved the cactus out of the pot). The color of its skin is still green, so I have hope. I took Lloyd out of the pot and planted it (temporarily) in half of a plastic cup that I filled with a little of the pot's soil. I have a feeling that some of you are cringing right now, but I'm a college student with limited resources, and I plan on taking more permanent steps once I have everything planned out. Anyways, I took it out because I was afraid that maybe Harry, who is at least 4 or 5 times larger than Lloyd, might be "hogging" the pot. I have absolutely no experience in cactus care, these are my first and I'm very attached to them (they were a gift from a very loved one). Any help that you guys would be able to provide would be appreciated.
