in the past i have bought some yellow clown goby's from my lfs..and on the 4 day i had them they came down with a fungus and died..even the ones at the lfs had the same thing..it's like the whole batch had it at the same time...and they all died..this past week end i bought another one and the same thing happened it died of fungus..and so did the ones at the lfs..? what's causeing these fish to get fungus and die? and it is always on the 4th day they break out with this fungus..is it stress related maybe from shipping? just wondering has this happen to anyone else that has clown gobies?
