when buying online you need to be sure you find a reputable vendor , I buy online quite often I had a lot of hit and misses over the years ,
I never had problems with fish coral from most vendors, I would be sure to ask others experiences as some online vendors sell garbage ,
another thing you need to do is find out how and who your stock is being shipped with,
some shippers have a bad rep on handling livestock,
always be sure your order has a 10day doa guarantee for anything that may not make it .
I bought this guy online with no complaints , he looks nicer than ones I seen locally ,
vendors need to earn your trust before ordering high dollar fish .
good online communication can be the factor if you buy from that vendor or not
