Q.Fish bone cactus
I received two cuttings of a fish bone cactus about a year ago and they are growing really well. My concern is the new growth is very thin, quart of an inch at most, the cuttings I was given are 2 inches across easy. Why is the new growth so thin? I have it in a window that gets some afternoon sun and it is hanging in a six inch pot. I have also fertilized it twice, every six months, sense I planted the cuttings. Any help would be great

They do start out thin, but they should thicken up over time. Make sure that the soil is a light orchid or cactus mix, so that the roots can have plenty of air pockets.
