Since I got Lotus, he's had a few missing bits from his tail. I thought it might be the filter inlet so I covered that with tights a couple of weeks ago. Tonight though, he has chewed it, just like Levi did-it looks a right mess 
Tank has nothing that would rip it, only thing I think could be stressing him is the reflections. He can see himself in the glass and flares a bit. I've had him over 5 weeks now, do you think he should have got used to it? There's loads of plants too so he can't see all the time.
I've solved Peacock's stress stripes by putting a bag over the tank. So nmaybe it was my cat stressing him? Don't know what to do long term though, maybe some sort of cloth cover that looks nice?

it's a pain and a habit that they don't seem to forget, not much you can do apart from changing scenery around a bit and keeping the water extra clean, hopefully he will stop and let it grow though there is no telling when the mood may strike again, I found mine went into his coco cave when he shredded as they need to be able to curl right round to reach it so I removed it. Watch him and see if he uses anything to help him reach and remove it, more plants may make things worse as he can use them to help.
From that list, it might be boredom or hunger. I'm going to feed him more bloodworm this week to help with healing too, so maybe that will help.
