Pls share a pic since we have no idea what kind of plant is involved or what you might be talking about. Offhand, I don't know a lot of succulents that look purple.

It's an Aloe of some kind, not Vera. Looks thirsty.

Are there rocks all the way down or is there soil too? Hopefully the pot has a hole in it.

The stones are at the bottom and top with plenty of soil inbetween. I watered it when we arrived however that's when it started losing colour ideas worried it was over watered. So have not watered it for 3 or so weeks. The leaves are very plump and not dry at all.

It should be in a pot with drainage hole, rocks at the bottom are not really good (only for very short period of time)

It could be Aloe juvenna, and red color is likely from some stress. Interesting that one stem looks ok, rest of them are looking thirsty. Leaves on most stems are not plump - they are curling since plant needs some water. Also, they should be closer together - at least as close as that 1 green stem. That is usually sign of inadequate light.

But do not water unless you repot it into pot with drainage hole. Potting mix should have at least lots of sifted perlite in it - 1:1 ratio is often recommended; not just straight soil.

BTW, it doesn't need to be repoted ..."due to its size"... Plant has plenty of room in that size of pot - but not drainage...(sorry for repeating myself).

Thank you
