Well, I bought this little tiny cactus about 5 years ago ... well hopefully it's a cactus. I think it was called madagascar something or other.

But i just can't remember what the name is.

Now it's about 2 feet tall , has 4 or 5 spiny branches with round, thick, leaves. It has bright pink flowers in groups of 3 on about 2 inch sticky stems. What the hell is it. Id like to know what type of fertilizer it enjoys and how long they last
