I thought I read somewhere on bluezooaquatics website that they qt for a certain amount of time. Not sure how long but do you know if this is correct? I'll try and find where I read that..I’ve had good success with the divers den part of live aquaria, but it’s been several years since I’ve ordered from them. I got a bonded pair of clowns from a company in California, https://www.arsclownfish.com. They’re doing great. Also got a few fish from bluezooaquatics.com that came in healthy. Also recently ordered from a recommended place in NY, they forgot to pack 3 fish in the box and a tang died before nightfall. They charged a fortune for shipping, totally wasn’t worth it.
