I think I know the culprit!

or nudi/slug snails got teeth

Ya, but I'm trying to recall when I've seen either of those make cause that kind of damage so quickly. The nudi that ate my leather made a smooth hole through it.

Ah, got it. Whatever it is is big and hungry.

This was the damage done by a large tritoniopsis species.

I dont know if you ever figured this out or not, but I actually had emerald crabs in my tank (I got rid of those evil jerks) after one of them attacked my toadstool leather, and very quicky took a HUGE chunk out of the side. It looked like a beaver had chewed out part of a tree trunk. My toadstool leather is luckily hearty and is bouncing back but it took a whole day for it to perk back up. But it did some damage and FAST to my toadstool leather.

Any light will do too. I stalk my tanks at night quite a bit.

Don't we all[emoji848][emoji849][emoji849][emoji849][emoji23] I mean it's one of the most interesting times to stalk the tank, all of those aliens come out at night...so who wldnt
