I think nowdays reef keeping is so much easy with advance equipment
and knowledge being share one another....
The old reefers have to try out the prons and cons and invest
large sum of money due to lack of marine knowledge in those old days
All i want to say is new reefers stay humble and learnt from the oldies
Once you decide going into this hobby ..prepare to spent some money
or else in the end the one who suffer is not anyone but are those poor
little fishes and nice corals
Sometimes i came across seeing ppl asking Q from the shop owner about this fish
and that fish, without knowledge , just buy all at one shot , esp those few dollars
damsels or clowns
For Goodness sake~~~ those are live stocks~~ they are not your lab testing
animals
My 2 cents worth
