Hey there everybody (my first post here) Well I am just getting into crabbing and have set up my crabitat! I'm in australia so I will give you the timeline of events in Australian time. Last saturday afternoon I went to the pet store and came home with 3 crabs - they are about medium size??? I got one of the plastic small tank things (as pet shops do *rolls eyes*) but because i had done my research; i knew it'd make a good iso tank so bought it anyways. Despite of all this; i did have my thermometer and hydrometer in there and over that 12 hour period my humidity and temp were perfect The next day I went off and bought my sand substrate (pet shop gave me wood shavings - as they do) and a new 2 foot tank. Added my sand, my water dishes, my food into the new tank). Except while I was at the markets getting the tank I fell in love with another crab - a purple pincher so he went and joined his new friends in the new tank. They were instantly at home and having a whale of a time together. I also got some driftwood and put that in for them. Monday came 15 new shells (i did have some before but not as many) and a hut, some trees, a piece of netting along the wall some cuttlefish and a giant scallop (name?) for bathing. They had such an awesome week together getting to know each other and their new crabitat. This past weekend just gone I have added 8 more shells and 3 new friends and given the crabitat a bit of renovation for practicality. However, although they seem very happy (they love their toys; they love each other), i have had my purple pincher have shell changes and I don't mean one or two as new shells have been introduced: I mean ALOT!!!! Sunday when I got him home and into the crabitat he changed shells within about 10 minutes (which makes sense as his shell was way too small for him). he really liked his new shell for a couple of days until Wednesday I discovered him to be in a new shell again (which was fair enough because again; he upgraded in size); THEN about an hour later he got some buyers remorse and went back to the previous one. About 1 hour after that I saw him checking out another shell - watched to see if I could maybe watch the change but alas, he figured out I was there and got scared. Came back to him half an hour later and he's in the shell he was window shopping And then on friday night he changed to another shell again. At first I thought it was so exciting that he was changing shells and that I was doing something right because it's a good thing (especially since purple pinchers are always looking for the perfect shell) but now I'm a bit worried that this is getting ridiculous and I'm doing something wrong Should he be changing THIS much? Is he just changing so often because I keep adding more shells and he has to check out every shell? Do i have enough shells (i have 23 total) about 12 of which would fit him nicely. HELP!
