It has a Gasteria feel to me. A close relative of the Aloe.
If it is indeed a Gasteria, the plant will go brown to red due to stress, which can be caused by lack of water, too much heat/sun, or too little heat/sun. A bigger pot would help. There is a good chance that roots have filled most of the pot and that there is little soil left, which means that water gets poorly retained and can lead to lack of water stress even if it has been watered regularly.
While you want to keep succulents in well draining soil and pots, if the water drains too fast the plant gets very little chance to retain any.
