I bought a pair of ghost shrimp from Petsmart yesterday and was wondering how long I need to quarantine them before adding them to my main tank. My fiance bought me four Histrionica loaches last week, so I'm ok with being overly cautious. I'd hate to loose my fish to a pair of 33cent shrimp because I wasn't careful enough.
Any suggestions?
Also, will they cause any problems for the loaches? The Histrionica are only about 3-4 centimeters long and are very young.
