interesting thoughts, i think a mix of both, like Atari I think people should try some corals and fish as beginners, it really helps to gain insight and experience (and enjoyment!). However, as Hara points out, the problem is that people rush into them because they are pretty/interesting and there tanks are totally unsuitable for them (but even the best of us have fallen prey to those gorgeous glowing corals under the
lfs actinics! lol)
I guess my opinion is that research is absolutely necessary in
sw, but it shouldn't get in the way of acctually trying your hand at keeping a variety of things! [just my opinion!]
