HCA: Hermit Crab Association

The average crab owner will never need anything more than a 2 inch opening, and even that is pushing it. Most crabs will choose to stay in smaller shells with their legs hanging out rather than have to lug around a huge and heavy shell that fits them to what we think is perfect. purpleperson, keep ...

This is my biggest guy, Hermie (named by the 5 year old who wanted me to take him as he realized he was scared of him) His shell opening is 2 1/4". I honestly always thought that PPs maxed out at 2 1/4" or 2 1/2". I'm asking as someone recently told me they have a crab with a 3" opening or bigger a...

Do you think it could've been an indo? or a marine crab?

Haha yeah I'm trying to figure out if the person telling me about it is being honest or if they're maybe exaggerating a little! ;p

To be honest it depends on the species for example indos would take up about 4 inches however ruggies may only take up half that . If you raise a pp to full size however, 3inches is about right Sent from my iPad using Tapatalk Yeah I'm talking about a PP. have you ever seen one that size?? Sent fro...

I used to do this too. What I did was take a 2L pop bottle, cut the top off, and left the bottom on. The I cut a side off (about 1/3 of the bottle) bury it the same way, and this way the crabs can dig from inside of it as well so they don't miss out on any digging room. They also can get below the s...

Beautiful tank did you buy this tank second hand? I've never seen one like it before but now I really, really want one lol

Thank you all! @krusty krab, we have no idea what breed she is :p her mother was part chihuahua and we have no idea what the father was. To her shoulder she is about 14 inches high but she weighs 30-40 pounds depending on the season! Her mother was much smaller. She was from a litter of four. She is...
