Highlights
Crassula rubricaulis (Ecklon & Zeyher): A shrubby succulent with long, flattened leaves. Sunlight transforms its coloration, bringing out vibrant red tones. It produces clusters of tiny pale blossoms in mid-summer. At maturity, this South African species reaches about 16.0" tall.
Soft succulents will not survive a hard frost, but if there is a risk of freezing temperatures they can be brought indoors to grow on a sunny window sill or under a grow light. They need ample sunlight, great drainage, and infrequent water to prevent rot. Pick containers with drainage holes and use well-draining cactus and succulent soil with 50% to 70% mineral grit such as coarse sand, pumice, or perlite. Water deeply enough for water to run out the drainage hole, then wait for the soil to fully dry before watering again.
Crassula can show tiny white or black dots on their leaves. These are healthy, water-transferring pores called "hydathodes" and not a sign of disease.

The fast draining, gritty soil is a good start! My only concerns are for your soil pH and sun exposure.
Sempervivum can grow in full sun, but they need to be acclimated to it first. Give them a few hours of exposure to the direct sun, then move them into shade for the rest of the day. Repeat this process, steadily adding or removing an hour or so as needed, until the plants can take the direct sunlight all day.
Soil pH is a different matter. The soil in the crevasses where Sempervivum grow in the wild are very acidic, even down to 4.5. Even S. calcareum, despite their alkaline tolerance, was found to grow in acidic soil. The point being that a slightly acidic soil is far better than an alkaline one for any Sempervivum. However, these plants are tough and a little alkalinity certainly won't kill them. They'll just grow faster and stay healthier in a slightly acidic soil.

Hello there!
Sempervivum are very hardy plants. They contain small packets of bad tasting chemicals, that deter deer and rabbits from nibbling on them. However, I do not believe this works on javelina.
We do not have Javelina this far north but, from what I read, they will eat anything. This includes Sempervivum.
I believe your best course of action is to invest in an electric fence, as you can't shoot them until a certain season.
You could also consider cactus or Euphorbia, which they won't eat due to the spines and poison. I'm sorry I couldn't be more helpful but… See full answer »

They are ideal for the outdoors. You can get them to survive indoors near a sunny, south-facing window or under a strong grow light, but even then they'll often languish and stretch.
Sempervivum are happiest and healthiest when they get lots of sunshine, gritty soil, great airflow, and cold nights and winters.
If you want that Sempervivum look, but indoors, I would recommend Echeveria or Aeonium. Theyhave a rosette shape, but handle sunny, indoor growing better.
I hope this helps!

Good question, but I have some bad news. This sounds like the symptoms of root rot caused by overwatering. You may just be watering too often, but it could also be that the soil you're using retains too much of its water.
Regardless, the first step you should take is allowing the soil to dry completely. I'm going to post a link here that will take you to our FAQ section that deals with rot more thoroughly. I hope this helps and I hope your plant recovers!
