Your donor rank that you bought? If so just go on a server and type in chat to find out. Also you are the one that bought it, shouldn't you know which tank you bought (unless someone else purchased it for you).
We have 9 baby ducks and a cat. Four ducklings died from starvation and had to be rushed to the hospital, but survived after eating an extremely large number of cookies. To this day, Pandahut has been the leading cause of wiggling.
