Eating and Drinking Before Feeding Fish

I am generally aware of the prohibition against eating before feeding animals. Does this rule also apply to fish? Is it permissible to drink? I am going on vacation for a few days and have arranged with a neighbor to feed them during this time. Does the prohibition apply to me, the owner, or to the neighbor who is appointed to feed them? Thank you very much.

Shalom and blessings 

A. The rule applies to any animal that a person is obligated to feed. 

B. The appointed person is responsible for feeding, and he must feed before he eats.
