Thanks to your clue, we (my mum and me) could finally find it: it's a Miltoniopsis. Both genera look really similar to each other, and that one seems to be known locally as Colombian "Miltonia".
Now we're trying to dig further into the species. I'm placing my bets on Miltoniopsis phalaenopsis.
I tried a keeping a few of those over the years without much success.
I have some tips, if you want:
Native species from your area will give you an easier time. If you can't find one that you like, look for species https://en.wikipedia.org/wiki/Climate_classification#/media/File:K%C3%B6ppen-Geiger_Climate_Classification_Map_(1980%E2%80%932016)_no_borders.png.
Most of them hate soil. You'll need a proper medium to grow them; it's usually a mix of tree bark, sphagnum, and sometimes charcoal (it helps to keep nutrients for slow release)
Light requirements also vary but most of them like indirect light.
Typically to water them you need to also water the leaves, so it's a good idea to use a spray bottle for that.
If you're unsure on when to water them, check when their leaves get slightly wrinkled. For me at least watering is each ~2 days now on summer, ~2 weeks on winter.
It's easier to over-water than under-water them, so do it preferably in the morning (as excess water will evaporate).
Once in a while it's a good idea to add some fertiliser to their water. Keep it really diluted otherwise it "burns" the plant. Usually I do this every 5th watering, so each ~10d on summer and ~2 months on winter.
Looks like the aloe succulent I have that shot upwards too. I don't know the name but as it was sold as a succulent maybe that will help narrow it down.
How big does it get ? That looks a bit like a baby plant, which is a more difficult to ID.
Some plants are leggy like that, but sometimes it's a lack of light. Does it grows toward the window ?
They tend to grow upward but in corkscrews. Not necessarily toward light. Yeah this and the other three are what I was able to salvage from the original that was maybe almost a foot or 14 inches long! It crept right out of the pot and I had to support it on another plant pot.
I don't have an ID for it I'm afraid, but I think it might be partially how the plant grows, and partially too much water. See the other comment on the thread: get a different soil that dries faster, make sure to have holes at the bottom of the pot, water less.
You need to get some drainage medium in that soil. Perlite, pumice or expanded shale. I do almost 50% of my soil as one/ a combination of the three. Granted I live in a very humid area so you may need less depending on where you are. Succulents need a lot of drainage and air around their roots. They're also really etoliated, they need way more light.
You may be over watering too, it's hard to tell from the pic but the one that's slumped over is a sign. Press the leaves, they should be firm with only a little give. If they feel squishy, they're over watered. New soil should help but you should cut back on watering as well, especially while they're recovering from being transplanted. Once a week when they're growing and once a month when they're dormant will do you just fine. It's coming up on spring so they may start growing soon. Id recommend you put them in some better soil asap, that way they can build new roots and get to growing under better conditions. Best of luck!
Not sure on the ID because that plant is hella stressed. Might just be aloe vera, but could be juvenna. There can variety within a species that may explain some of the irregularities I'm seeing. Do you have a picture of the healthy mother?
The soil needs to dry out between waterings to encourage root growth and prevent the plant from falling over. Chronically over watered aloe will get floppy and weak.
They don't do fantastically with a hot soil, I cut my Fox Farms Ocean Forest with coco coir and perlite at about 30/50/20 and I have gotten aloe vera to be about 30" wide 3ft tall with more babies than I know what to do with. The only time I fertilized was when I went up a pot size and I just added more of the same soil mix, planted the babies in it too. So if you are using miracle grow or an uncut hot soil, that is bad.
I second this opinion, albeit with less fancy words ^^' also feeling sillly that I did not catch it on my own.
Do you think the one by the window is doing better because more sunlight helps it dry faster ?
Probably. The sun exposure only helps you so much until the plant covers the soil and helps trap moisture, then it comes down to the soil mix and the material/color of the pot.
Aloe is stupid tolerant to neglect, I have had big ones I didn't water for a year and they kept on trucking after a good soaking. On the other hand, I have had ones I gave away die in weeks because people kept watering them instead of letting them dry out between waterings.
They stretch like that when they aren’t getting enough light. It looks over watered as well. The soil looks very wet, you will want some that drains better and dial back the waterings a tad.
They were all just watered a day or two ago which is why they look wet. and are all in succulent mix with rocks in the bottom go help keep them from tipping over and for the water to drain out.
It looks like spider mites to me. I have a similar issue and I'm using neem oil to spray all surfaces of the plant every 1-2 weeks until they go away. There are some other treatments you can look up too.
Agree with spider mites, pretty sure I can see webbing between the leaf tips.
Neem will work, so will insecticidal / horticultural soap and it smells less bad. Heck they’re soft-bodied, you could probably spray 50% isopropyl and kill them too. I like the soap because it’s really cheap and safe for pretty much anything without farina / epicuticular wax (I feel like some begonia Rex aren’t a fan either).
This is a good sized infestation so I would recommend starting by rinsing the leaves really well in the shower or with a hose. After debulking the colony, then use insecticide.
Check your other plants too OP! Mites are not particularly particular.
Definitely spider mites, I've gotten rid of them by giving them a good spray down with my shower head, wiping all the leaves with damp paper towel, and then dousing the plant in miticide (i used safer's end all, it comes in a yellow bottle). I did 3 separate treatments 3 days apart. and then kept them quarantined for a month to make sure i got em all. I managed to get rid of the mites on most of my infested plants except for my parlor palm which i ended up throwing out. There's other, more environmentally friendly options you can google but that's what worked for me.
Make sure you get all the nooks and crannies, including the underside of the leaves, stems, and the top of the soil. Those buggers are prolific and if you miss some then they come back quickly.
