egg crate

[degbowl]

I am thinking of getting a yellow watchman goby. I know they are jumpers. I am using a red sea prizm skimmer. Because of the skimmer I can't fit my glass top on my tank all of the way. I have a large opening in the back. I have read that using egg crate I can cover the openings so the fish won't jump. I know that I can get it at Home Depot. Should I just go into Home Depot and ask for egg crate? Is that the real name of it and what is it really used for? I just want to know where to look in the store. Thanks!

go to home depot and look in the lighting section, if you cant find it ask for eggcrate, but you'll most likely find it in the lighting section

I found the egg crate. I have plenty left over. I had a glass top that I kept the front part that was the lid. I made a piece of egg crate big enough to fit the rest of the tank. I made cut outs for the skimmer, filter and cords. The egg crate was the same width of the tank and I didn't need to cut for width. I can put something on it to keep it held there because I have the glass lid to open up for feeding. Now I can get a fish and not worry about him jumping out.
