In a small to med. size tank, yes, most tangs are harder to keep happy since they are great swimmers & like more than 3 or 4 feet to zip across. Lionfish are fairly easy to keep, but they have their own disadvantages. They have a very potent poison in their dorsal spines (as someone who once had two "needles" of poison injected into his finger can bear witness to). They are big eaters & will need a high powered skimmer to keep the water quality high.
If you are really interested in keeping med. to large fish, and space is an issue (ie. have only 4' to play with), consider getting a 120g with a good size sump underneath. The 120g is 4' by 2' by 2' and is big enough to house a tang (like a yellow or Powder Blue) if you do the aquascaping properly and leave lots of swimming room. Ideally, most tangs should have a 6 footer, but I would be comfortable putting one in my 120g fowlr.
The big question you have to decide is whether you're looking to do a fish-only (much easier & less expensive) or a reef (can be more interesting, but much more challenging & more expensive side of this addiction).
Next week, if you have time & are in the Burnaby area, feel free to drop me a line & come on over for a visit. I have both fowlr & reef setups so you can see the differences & discuss your ideas.
