first let me say your lucky on the father son bond , I so miss my son I haven't seen him in over 15 years , he took me and my X wife's divorce very hard , I've always stayed in close contact with both him and his sister , my daughter is now with me even she try's so hard to get my son to come out to visit , my son has a slight mental disorder and doesn't take to change well , but this dad will never stop trying or give up ,
Ok now back on track , sorry about all the fish you lost , I always try to make it a point to order the expensive fish online as they get a depending on the vendor 7 to 14 survival guarantee most LFS have no sort of guarantee its more a S O L policy ,
I know it's hard not to see what your buying on line but I have not once been unhappy
and I've always had a 95% survival rate ,
fish that are more prone to Ick should be quarantined for no less than 30 days IMO and introduced slowly to the display tank , I have also noticed with tangs and angels that were QT if you catch them in the net and can transfer them into your had out of the net being able to bring them closer to the rocks for release they tend to do better , as they can hid and not be picked on and come out on there pace ,
It's not easy loosing 1 fish yet alone a handful , small fish a inch or smaller I have always added in numbers big fish over a inch and up 1 at a time it's less stress on the fish this way IMO
) I still lost well over $300 worth of tangs to marine ich!
