I suspect that these shells, from what I have seen, have better chip resistance than a regular shell, and I would be surprised if a crab could do that sort of damage bumping the thing. Falling from a high perch onto a rock, sure, but bumping the glass? Nah. I have some pretty strong crabs who make some fairly loud noises on occasion when they hit the glass in their tank. They have not chipped their regular shells I would be surprised, very surprised if they could break one of these. Blown glass has considerable strength depending on the glass used.MacandHunter wrote:There is a big shell shortage in the wild. And I would never buy a glass shell myself because 1 - there are cheaper alternatives and 2 - my guys bang on the glass all night long and I'd be worried it might chip off.
Speaking of which - what kind of glass is this?
LOL - might be interesting for a while though - I think there are a lot of assumptions made about how crabs interact with their shells and these could be a great learning tool.And I don't want to see my crabs ugly butts. Extra censorship near the bottom of the shell, please.
Certainly far more attractive and durable. The inside should be smooth - just like the MOP lining most crabs go for. And most importantly - I think we can assume that no one is busting them out of one shell to go into the glass one's.But I think these are better than that plastic shell idea.
Better suggestion: What can be done to reduce the shell collecting worldwide that disrupts the hermit crabs life cycle and affects myriad other organisms as well. There are some papers out there that suggest that old shells may be a significant source of rainwater collection an the only source of fresh water on some islands.What do you think of using your profits to make shells for crabs in the wild?
Life - it is a complicated business.
