Fish! I went to hawaii and went snorkeling and saw all the colorful fish. My fav was a yellow tang. Then I went suba diving later there and I knew I wanted to keep them in my tank. Later found out about coral
Are we talking about the hobby as in fishkeeping as a whole, or reefkeeping specifically? I started out with a freshwater tank because of fish. However, corals are what brought me to the salty side.
Fish and corals were cool but the "live rock of the 80's"
Is what did it for me.
There was so much color and life compaired to today's.
It was stacked up in every lfs I visited.
Hermit crabs actually. Short story really, walking in the sound, picking up hermit crabs, went "Hey, these are neat" did some research and here I am 15 months later with a 90 gallon reef
