Saltwater Aquarium/Feeding saltwater fish


I am wondering what to do about feeding my fish when I go away on Vacation for 9 days?? I have just moved to a new place and don't know anyone to beable to come in my house to feed them.. We have a 29 gallon Bio Cube with a metal hali light and a glass cover .. So there is no way of putting a auto feeder on that.. The light would melt it and removing the glass top would let my fish jump out.. How long can saltwater fish go with out a feeding.. We already have a light timer on it that works perfect.. Any inforamtion would be so much help .. Thank-You Valerie

Hi Valerie:

Although I don't recommend for anyone to go without feeding their pet fish for 9 days; however the truth is they should be fine, and there are naturally occurring food items in aquariums, like: planktons, copepods, amphipods, and algae.

In conclusion I'd imagine they would be fine for 9 days.

I wish you luck with all your saltwater aquarium endeavors.

I possess over twenty-five years of hands-on experience and knowledge in the ecology of aquariums. Beyond the traditional, I have successfully tested and sustained environments that have been uncharted territories for hobbyists, for decades. I am the first to admit I don't know it all because there will always be something new, amazing, and exciting to learn about, as discoveries are made. It's a hobby one can never outgrow, or grow tired of.

After High School, my experience and love of marine animals influenced me to take up studies in Marine Biology. Throughout college, I studied Microbiology with an emphasis on Marine Life, as well as numerous other sciences. I continued to advance in this hobby, by building a dozen or more saltwater ecosystems all utilizing Microbes as the major source of my filtration method.
