I would personally go with the 29g biocube. Im only saying this as a master of the obvious in that it has five more gallons of poop diluting power, but its usually only ten more bucks than the 24g aquapod and that in my opinion is a better deal. With that said, I own the 24g and I like it. Its a nice aquarium, but recently I had to replace my multiple year old lights and had to basically break the cover of my hood off. All the screws are 'stainless' but thats no competition for years of saltwater abuse. They all corroded and basically disintegrated when I touched them with a screw driver, and what ones didnt disintegrate just stripped and I had to take a pair of bolt cutters to break the plastic pieces around the screw so I could get the lid off. It was a pain and a half. But either way good luck and the best advice I can give is do frequent, gradual water changes instead of big ones (25%) at the end of each month. fish loves it.
