I have had a very happy, healthy,fat,eating out of my hand, sailfin tang in my tank for a while now.. I came home today and got some food and stuck my hand in the tank waiting for him to come up and eat from my fingers as always and..............................Nothing!... I have done an extensive search and there is only one possible scenario, for some reason he jumped and the dog ate him. no other possibilities. he was there yesterday and I have no clean up crew that would eat him. very bummed!
