Personally, I love the biocubes. I had a 29g for a couple years, just sold it recently. But yeah they are a good starter tank. The only thing I would do is get the 29g version, you can keep alot more fish in it than the 14g, trust me on this one lol. The only thing I changed out was I added a media basket to the back compartment to make filtration easier and maintenance easier. It has lighting that will allow you to keep soft corals and lps
corals which is pretty nice. (lps
are the wavy corals and softies are like zooanthids).
So yes, I would highly reccomend one.
