What do you feed your baby clowns? Flakes and pellets? If so, i can recommend the
eheim auto feeder. I use two of them on two tanks and they have been great. I got one for holidays like you, but now they are employed every day to add an extra feeding in the mornings and afternoons while I'm at work. Have not had any issues with them. I've seen them sold at just about every local fish store that I've been to. A couple of concerns that I've read about autofeeders in general is 1. you can accidentally dump in too much food and 2. they can clog due to humidity. Well, neither have been an issue for me. It is vented quite well to prevent humidity clogging and you set the amount of food to dispense and it will never drop more or less (unless it runs out of food of course) than what you set.
edit: If you are going to use one of these auto feeders what I would recommend getting also is a feeding ring. This way you can drop the food into the feeding ring and keep it contained there. Otherwise the food will quickly float into your overflow (assuming you have one).
