If it works for you, then why not!

There is always controversy.lol
My 155 has 5 tangs (Yellow, Hippo, Sailfin, Powder Blue, Purple), a Majestic angelfish, a Flame angelfish, Niger trigger, Marine Betta, Mystery wrasse, 4 Line wrasse, Possum wrasse, Bengaii cardinal, Snowflake clownfish. Plan on adding a few more smallish fish.
I do have corals, and so far all is good. SPS are growing, and do have color. LPS, zoa, leathers, goni & alveopora are all growing. Oh, and my 5 year old maxi clam is also doing just fine.
So are you crazy? NO! Are you addicted? Heck YES!!!!!!!!!!!!!!!!!!!!!!!!!!
