Here is my ZZ Malau that I have had since about 1.25 inches. In the first picture, the FH was at about 1.5 inches, in the last picture he was at about 5 inches. The last picture was taken about 4 months ago, shortly after I took the last pictures, the Malau got sick with Hex. He didn't and wouldn't eat anything for 2 and a half months and became extremely malnourished/skinny, I thought it would eventually die and I considered euthanizing him but didn't. Just about a month ago, it started eating again, but in small amounts. I'm trying to get him back to a healthy weight, but it may take awhile since he seems to be picky with types of food now, a habit he didn't have before he got sick.
