I have a 100 gal reef tank and my fav fish has got to be my Flame Angel. I have a few Picasso Clowns that are cool. Actually I love my inverts more than anything. Fun to watch them Going to be sellling it to make room for the chams, priorities........ lol
My favorite fish (if you classify it that way) is and will always be the box jellyfish. Their beautiful but yet the most poisonous marine creature on earth. My other favorite is the lionfish. Their by far my favorite actual fish. Their stunning to look at but poisonous in every way.
I used to have african cichlids I loved them but seince fish cost so much more than herps to maintain I had to tear down there tank I still have some of my cichlids in my reeves turtles tank but only about 7 of em. Before I used to have 60 there an amazing and easy to care for show fish and when you get a whole bunch and they swim around and all there colors combined there sooo pretty.
