I have an alien eye echino that I can't seem to make happy. It is receeding and I can't seem to help it. I was told that indirect light was best for it. I kept it under an overhang for a long while (maybe 6 months). It never showed any growth but seemed to be ok. Then it started receeding. I found other sources that said to give them light. I moved it half way up but that doesn't seem to help either. I am out of guesses.
