The Australian Museum Science Festival began today - yay science!!! I had excellent fun helping to shepherd extremely enthused children from one exhibit to another. Shark in a bus (its a shark - in a bus!) and the native wildlife exhibit were particular highlights.
Leafy sea dragons hunt shrimp and plankton species with sensitive sensory organs allowing them to detect approaching predators through water movement. Using camoflague (they move through the water in such a way they seem to be floating kelp) and stealth to approach their prey, dragons then suck up their victims with great speed. With an astonishing 90% success rate they are one of the most efficient predators on the planet.
Sharks constantly grow new teeth to replace those that go missing - some grow 30000 teeth in the course of a lifetime.
Kirby, the most relaxed and patient Eastern water dragon in the world.
My new Fluval Spec! Eee! Its taken an age to cycle but at last it is ready for fish. I've put in my new female platinum white elephant ear Odette until I'm sure Merrick is completely healed and the water parameters are stable.
I'm experimenting with a simple Iwagumi style in the Spec since my other tank with aggressive females will always need to be dense so they can hide from each other when they have their spats. The fissiden moss, a rarer species than I've encountered before, will slowly grow to carpet the sand.
I wasn't sure about the nighttime effect blue light at first but it really is rather peaceful actually.
