I was just curious as to whether or not people ISO their new crabs or not. If you do ISO, how long do you keep them in ISO before moving them over to a main tank? Those of you that don't ISO, do you bathe them prior to putting them in with your crabs...do you bathe them all (including current crabs), etc... I recently got into the crab world and now have 8 crabs in a 40 gallon and recently bought 5 that I am keeping in the 10 gallon (1 of the new crabs already died of PPS 2 days after I rescued him from the nasty place). Does your new crab rules depend on the conditions the store had? Or whether or not it was the same store as the last purchase, same shipment of crabs, etc. Originally I bought two sets of 4 crabs from the same store, within the same shipment, within 2 days. So I put them all together immediately. But the newer crabs are from a nasty little pet store, bad conditions, and were bought about a week later. The crabs thank you for any info!
