Attach below is the photo I take from the plant. Any help in identifying this plant is greatly appreciated. It is relatively spiky, the person that sold me this plant told me it is a cactus but he forget the name of it.
Thanks, I went to google it and notices the similarity. I think it might be varities bevilaniensis or imperatae Is there any specific care for Euphorbia milii (Crown-of-thorns)?

Don't prune it. Personally (I grow true E. millii) it looks like one of the many intergeneric hybrids to me. That makes absolutely no difference to how you treat it, though; if you follow Bluewing's advice it will do just fine.
I've found that if I let it go too dry between waterings, it will drop it's leaves. My own, I water thoroughly once per week, but they are not in large pots. I also have them in a west window through the winter. They go outside for the summer. They bloom and grow for me 12 months of the year, so I have to continue to fertilize.
Does fertilizer really works on them? My E.mili is like 4 years old and I haven't really fed it fertilizer before, I only use those "black fertilizer soil" for it. Does those "mix-fertilized soil" works? Also, the place I lived in have no seasonal change. The temperature range from 25°C to 33°C throughout the year.
It wouldn't hurt to add a little fertilizer for your Euphorbia milii.These plants can be in flower with some light feedings and sunlight almost non-stop, which includes thru winter.
