Information about the hobby
There are lots of different sources for information, but finding exactly what you need to know can be challenging
Knowledge is nowadays often shared in the form of text blocks or dicussions. This makes it hard to access for others
A lot of information is subjective. The best example for this is the required tank size for fish. There is not just the one right answer for that question
It is hard to keep track with the sheer amount of color variations and trade names for different corals
Buying and selling
Origin of offered animals is often not communicated to buyers
Offers often do not contain enough information about the animal or products
Buying and selling within the community is a lot of effort with the current tools available
Keeping the overview
A lot of reefers do not keep a list of inhabitants and equipment for their tanks
When getting advice, it would be helpful to share tank setup
There are no tools available which really simplify this process for reefers
