All pictures I see today from my perspective are rather small colonies and everyone is a reseller to some extent.
Is this perception correct or just a bias from looking at forums? For example someone might show off a Walt Disney 3 or 4" tall as show worthy fully grown, where in past you may have gotten a frag that big of something less expensive.
Growth rates are always subjective so I will leave that alone.
Let's see the other side.
Since your pointing fingers at others for having smaller colonies let's see your tank with larger ones.
Now if you do have larger colonies, you would not care about other people tanks with smaller colonies. You will show it to everyone and will be talk of town.
The way I see it corals have changed. Back in the day you were growing green slimer, bird nest etc.
There was hardly any hard sps in any tanks. Knowledge and education didn't exist.
Today we have smaller colonies but more color and we can grow harder species in our tanks.
Show me something similar in color to Walt Disney from 2000 in colony form from a personal tank ?
Even LPS, even Shrooms. Did bounce existed in 2000 ?
As for reselling, that exists in every thing nowadays.
People sell branded clothes, electronics , furniture etc.
Some of them are only 10 percent below cost.
I don't see it as bad. Even if the reefer marked it 10 percent below store I am happy. If I am not then there is always someone else I can buy from.
I don't see people selling as bad. As for smaller colonies what they do is their things.I do understand to buy corals every month costs upwards of 2000 dollars sometimes. That money has to come from somewhere. Anyone buying high end coral knows the pressure of coral dying, spouse lol etc.
Now I could be proven wrong in every thing that I said. It's OK, atleast I will be more knowledgeable.
