as far as I know, those colored cacti are glue onto the green part cacti. neither will really grow. unless you're lucky.

The moon cactus is grafted onto a host — in this case a dragonfruit. The moon cactus will grow! I think what we’re looking at is just mechanical damage

ah yes grafted. I knew glued wasn't the right word. it was early for me. lol
