This was earlier this week and now it's a good half an inch or more shorter, there's no black around the edges, he has to be really flexible to be chewing it off, there is nothing in his tank that he could be ripping it on (took out everything but three silk plants including substrate just in case) there is always the clear new growth going on one day and then the next he's got even less tail! He's such a problem child!
