Hello, I am Nikki and I have 4 human kids (Ben - 15, Romeo - 13, Lexi - 12, and Maia - 11), 5 dogs (Bo - 7 year old pit bull, Vice - 2 year old pit bull, Neeci - 3 year old chihuahua, Ellie - 2 year old chihuahua, and Cali - 1 year old chihuahua), and 4 new hermit crabs (Kermit- medium size PP, Candy - small size PP, Spinner - small size PP, and Midget - smallest, small size PP). We just got the hermit crabs a week ago. Maia wanted hermit crabs so I started researching and decided to give it a go. Kermit and one that died a couple of days after bringing them home, Shelly, came from PetSmart and the other three came from our local pet store. They are in a 20 gallon high tank. They are very interesting little guys. They are all staying buried during the day except Kermit who sometimes comes out midday and walks around and never fully buries himself. I got a shipment of extra shells yesterday from HCP and Kermit, Midget and Candy have changed shells already although Midget ended up putting Candy's old shell on instead of a new one. Kermit chose the largest of the ones I got so I ordered the medium shell pack too so that he would have more to chose from. I had no idea when I got started that this was such an all consuming hobby but it is addictive and I spend a lot of time thinking about what they need and looking for more stuff for them to make them as happy as possible.
