Also, is it normal to have water on the glass? If not how do I get rid of it besides wiping daily?
Thanks!



The deepest is 7" but I thought it needed to be 3x deeper than my biggest crab? My biggest fits inside a shell with a 1.5" opening shell. Another question, how do you determine what size your crabs are? Small, medium etc?hermitcrabdc wrote:How deep would it be if you just evened it all out? If it's 6 inches you won't even need more sub. It's hard telling from the picture how deep it would be. I'm not sure if mixing moss in would be a great idea, unless it was really fine moss.
Do you spray each day? That can help the humidity boost. When I had heat lights they killed my humidity. I was a battle to keep the humidity up just for a few hours. Once I got my ultratherm that evened everything out. It might help once there's some plants in there, you can spray the plants and they'll hold some of the water.
You could try putting the moss in a bowl if you think it'll help, not sure it will help much
6" of substrate is only sufficient for very small crabs. I have 13" in my 55 gallon and around 10" in my others.hermitcrabdc wrote:How deep would it be if you just evened it all out?

That is the general recommendation, at least 3x as deep as your largest crab stands tall, but not less than 6 inches.CrabbyHermit wrote:I read is suppose to be 3x the depth of your biggest crab?
So glad to see this! Our biggest is definitely bigger than a golf ball and smaller than a tennis ball. Put some new larger shells in today (finally!) and they seem to be popular with the little guy. I'd been worried about sizing him correctly and finding appropriate shells-- I was so worried the shells I found wouldn't work out but thankfully they did. This extra info is a huge help, also-- thank you!landlubber wrote:To answer your question about sizing-it's not an exact science. If you size by the shell you could have larger crabs in smaller shells and vice versa. If you size according to the chart on the site which basically measures space between the legs when walking normally means you have to try to get them on the bulls eye and willing to walk normally right over it and do it enough times (because they are likely to be moving fast and going in an opposite direction to where you want them to go) to really get a good measurement. If you hold them over the bulls eye by the back of their shell their legs splay out and it gives an inaccurate measurement. As far myself, knowing the subjectivity in measurement I just eyeball them. If the crab in its shell is the size of a marble they're teeny, the size of a golf ball they are medium, the size of a tennis ball they are larges, and the size of a baseball is a Jumbo. Most of my crabs are in between these sizes, like I have two mediums who are larger than a golf ball but not as large as a tennis ball.

With substrate, more is better because the more room between molters and crabs digging for fun the better off the molters are because they are not as likely to be disturbed. It should be at least 6 inches, but more doesn't hurt.
