Hygrophila polysperma, Caulerpa taxifolia, and Egeria densa are examples of aquatic plants that are banned in Indiana.
The 28 banned species are outlined in the Indiana Natural Resources Commission’s new Rule found on the state of Indiana’s website.

Darwin hypothesized in 1880 that most species could not disperse across the marine barrier, and Baums’s study is the first comprehensive test of that hypothesis using coral.
This is an amazing tank. Robert upgraded to this 400-gallon aquarium around New Year’s Eve 2010 from a 130-gallon tank and it certainly shows that he has a “salty-thumb.” It is mainly an SPS-dominated aquarium measuring 250 cm x 80 cm x 80 cm (~ 8 ft x 2.6 ft x 2.6 ft).

Urban development and agricultural activities increase nutrient levels in local waters. This becomes especially problematic around reefs as higher nutrient levels not only bring on eutrophication but also favor increased filter feeding activity.

This video shows never-before seen footage of a deep-sea angler fish, Chaunacops coloratus. In it, a summary of recent work by scientists at Monterey Bay Aquarium Research Institute, Moss Landing Marine Laboratories, and Monterey Bay National Marine Sanctuary is presented.

What this person did was to open up an inexpensive $10 smoke detector and solder wire leads onto either side of the battery test button.
This fire coral (Millepora alcicornis) is entangled with a plastic grocery bag on Graceland Reef, Florida.
The Florida Department of Environmental Protection, Florida Fish and Wildlife Conservation Commission, and Palm Beach County Reef Rescue coordinated the cleanup effort this past July with seven volunteer dive boats from three counties participating in the event.

We all know how important it is to properly feed our corals. Properly fed corals are more robust and healthy, and zooplankton capture can even help them recover faster from bleaching episodes.
