Seaweed clips are a convenient way to feed herbivorous fish like tangs and rabbitfish. While they are relatively inexpensive to pick up from your local fish store, it is convenient to just print them instead.
Researchers at the University of Queensland have concluded - based on Intergovernmental Panel on Climate Change analysis - that it would cost one year's worth of GDP growth over the next 50 years to stabilize global temperatures.

Climate change drove coral reefs to a total ecosystem collapse lasting thousands of years.
Banggai cardinalfish, Pteragon kauderni, are the referred to as the "guppies" of the marine fish breeding world. However, determining their sex in order to form pairs is sometimes problematic.
