I have one too
It can be hard to start one up ... 14 gallons is really small for a reef tank though, it's going to be much for difficult to keep it stable and you'll have to be on top of the water chemistry (check it daily
) ... typically beginners should go for the biggest size they can for that reason ... but they are pretty pricey
I think the lighting will be the biggest challenge, as it can be hard to find high powered lights that are short enough to fit 14 g. If you're planning on keeping coral you will need a light intensity of at least 4 watts per gallon, otherwise your coral will die. You may have to go with hallide, which is unfortunately ... the most expensive lighting (but also the best)
Also with 14 gallons you shouldn't keep more than one fish. The rule is typically 1 inch of fish per 10 gallons of water. You could probably get away with 2 percula clown fish though (always buy clown fish in pairs) if you're really diligent with the water changes. Give it plenty of time to cycle before you add any fish and coral ... at least a month.
Oh yeah wanted to add, if you have any questions feel free to ask any time!!
Good luck with it.
