Reefkeeping España

There's something about this reef aquarium video from Spain that simply makes us happy (it's definitely not the video quality). Between the mix of healthy soft and stony corals, active fish full of personality (complete with handfeeding), and the upbeat soundtrack, we're reminded why reefkeeping rocks.

This two year old reef aquarium is only 320 liters (85 gallons) but appears much larger thanks to its aquascaping.  Large corals corals populate both the foreground and background, with layers of stony coral colonies "sloped" in between; The sum of this aquarist's aquascaping effort is a convincing illusion of depth and perspective.

Here are the few details we found:

  • 6x54 watt ATI T5 fluorescent lighting
  • Calcium Reactor
  • Ozonizer
  • Deltec 2060 protein skimmer
  • Ecotech Marine Vortech MP40 and Tunze Nano Stream

A team of scientists has uncovered why clownfish make sounds. It is not to attract mates. Instead, it is to establish their hierarchy within a group and to defend their breeding status from other individuals.

Social animals usually congregate for protection or mating or to capture bigger prey, but a University of California, Berkeley, biologist has found that the terrestrial hermit crab has a more self-serving social agenda: to kick another crab out of its shell and move into a larger home.

Corals under attack by toxic seaweed do what anyone might do when threatened -- they call for help. A study reported this week in the journal Science shows that threatened corals send signals to fish "bodyguards" that quickly respond to trim back the noxious alga -- which can kill the coral if not promptly removed.
