Hi & welcome! It's D. 'Lemon Lime.' From what I can see in the pic, it looks fine.
Care would be the same for any version of D. fragrans. Water when dry. Whenever possible, avoid tap water by using rain, distilled, or condensate from a dehumidifier or A/C. Repot & change soil every 1-2 yrs. Prefers to stay above about 50°.
Which way does that window face? If not E or W, it may not be getting enough light.
