Set adrift with a pair of Harlequin filefish

There's no debating it: Harlequin filefish are amazing fish. And there's just something magical about following an inseparable mated pair cruise the Maldives together. I could do a whole lot worse than become a harlequin filefish in my next life.

Crystal Red Aquascape

We are long overdue for a shrimp tank post. An aquascape full of Caridina shrimps is arguably just as engaging as any aquatic exhibit you can set up. This nano aquarium displayed at the 2015 Art of the Planted Tank (held last week in Hanover, Germany) is a bustling metropolis of lil' busy-bees.

This aquarium proves that the phrase "My tank it too small" is not a valid excuse for a boring aquascape.  It's all about scale and balance.  I could spend hours watching these little dudes tending their gardens.

Bacteria in sponges harvest phosphate, clarifying reef waters

Bacteria are the yeomen of the reef; it is these microscopic background workers that keep the whole coral reef 'machine' churning. For the first time, scientists have identified bacteria growing on sponges are responsible not just for nitrogen reduction but also for pulling phosphorus out of the water.

The copepod from hell

The copepod from hell

Find me a cleaner shrimp, STAT!

Ich, flukes, and velvet parasites are terrible enough, but they're no where near as grotesques as what this poor dwarf goby is suffering from: a gnarly parasitic copepod literally sucking the life out of its host . And you thought you were having a bad day

Some creatures use electricity and vibrations in sex (and this can be dangerous)

Finding mates using electric signals. Derek Ramsey, CC BY

Most animals use touch, smell, hearing, taste and sight to identify and attract a mate (that goes for humans too). But some species [like Ghost knifefish] have additional and unusual weapons in their sexual armoury – the ability to sense vibrations and electric signals which indicate that a similar creature is in the vicinity.

Are yellow tangs the most acrobatic fish?

There are many reports of seemingly healthy yellow tangs (Zebrasoma flavescens) doing back flips and even swimming upside. As far as we know, there is no explanation for this strange and awesome behavior.

Here is a video of a yellow tang doing what appears to be voluntary back flips.  The specimen appears fat, disease-free, and not under any distress.  The owner report his tang performs its circus act randomly and irregularly (says the owner: "He just gets in his silly moods sometimes and does this.")

https://www.youtube.com/watch?v=knEBiSyP7ko

There are many more anecdotal accounts of yellow tangs performing similar "tricks"; just do a search for "tang flips" in any saltwater aquarium forum.  A year ago, Reefbuilders reported about a yellow tang that seems to enjoy swimming upside down (video below).

What is it about this species that makes them perform these strange acrobatic feats?  Is this just yellow tangs having fun?  Showing off?  Fighting their reflections?  Buoyancy problems?  There are not enough reports (both in captivity and in the wild) to say these acts are natural behaviors for yellow tangs.  Yet, there are too many reports to think these acts are isolated phenomenons.

Mystery "tall, short-bodied" anthias

Mystery "tall, short-bodied" anthias

Looks like a compressed anthias, doesn't it?

We have a head scratcher. Christina Jayne of Union City (CA) LFS Baja Reef photographed this anthias or perchlet acquired at a wholesaler. But what species is it? Is it a hybrid? A juvenile of a large fish? A deformity? Unfortunately, the wholesaler did not have any information about this specimen.
