ASFs in tanks destroy silicone!

has anyone had any issue with this, i have them in tanks and they are destroying the silicone that bonds the tank together, should i be worried about this??:confuzd:

Almost all rodents do that in my experiance. They can't chew far enough into the joint to "unseal" it enough to cause structural issues.

That's my $0.02 on it anyway.

Yeah, not a problem. All rodents do it.

good, i was bout to throw them all away and buy new ones!

Just don't try to use it as a fish aquarium!
