Sometimes people dont want a dog crossed 4 ways you know.
Cant find mini schnauzers at the shelter, but they sure are fun to have. Yes a pound dog might make a great pet, but sometimes people are looking for something in particular rather than in general.
Who wants some light brown acropora? Sure, it will grow just fine. As for me, I have little room in my tank and like to use up space with really neat looking stuff. I have some ORA corals and can say they are very nice corals. The frags come as mini colonies rather than a "twig". They have some outstanding colors too.
Name brand corals cost a bit much, but most are as colorful as they are $$$.
Chalice corals are probably the most $$$ things I have seen, but some of the crazy priced ones are also the most beautiful I have seen. Once you see them, its hard to give up sand bed space for some random brown blue chalice (priced great).
Now I am not one to go spend a fortune on anything, but dont judge the people that spend a bit more than me that are getting outstanding colors too. Of all the beautiful things in the world, none match things that live in our tanks.
Living diamonds some of those name brand corals are...
