I'm setting up a tank for a friend of mine. She loves fish, and wants to have some very badly, but doesn't want to do any work.
She's agreed to do water changes, but has trouble with the feeding, worried she'll feed too much, or forget, or her kids will feed them after they've already been fed.
This brings me to the topic of auto feeders.
Do these work? Do they work well? Is it obvious when they're broken (aside from skeletal fish)? Is there a "good" one? How hard are they to clean?
