Hermit crab being strange

[Jakey_cakey1]

Hi guys so I have two hermits one is your typical scarlet hermit normal very docile all it does all day is munch of algae and left overs but my other is a white clawed rock hermit and it seems to just literally run laps round the tank and has done since I got it maybe 3 months ago it’s molted twice and has plenty of shells to choose from it will wear one shell for a day then go back to its old one am I being an idiot thinking there’s something wrong with it or is this just normal I looked on Google and it said it may be just “exercising” but the more I think about it the more I feel like somethings wrong with it (it’s cleaning day tomorrow so I apologies about the algae)
