This summer, we reported on three newly described Trimma gobies: T. pajama, T. meranyx, and T. zurae. Unfortunately, we only found photos of the first two at the time, and boy were those gobies spectacular. We now have photos of T.zurae.

A Lego auto fish feeder

Lego is the new duct tape. There's nothing you can't build out of them. Osamu Mizuno assembled this auto fish feeder out of mechanized Lego parts. Admittedly, the system is not practical and probably not all that reliable, but it's just plain ol' cool.

Lego isn't what I remembered them to be when I was a kid.  Nowadays, there are servo motors, gear, articulating parts, and power supplies for Lego that elevate them from simple building blocks to something that almost requires an engineering degree to assemble.  With some 3rd party parts and mods, you can create amazingly complex, functional builds ... like this automated multi-tank fish feeder on (Lego) tracks.

There isn't any accompanying information with the video, so we don't know the details of the build or why Mizuno even built this contraption.  Sure, a commercial fish feeder would be a lot more reliable, practical, and affordable.  But if that's all Mizuno did, I wouldn't be blogging about it, would I?

Certain types of corals, invertebrates of the sea that have been on Earth for millions of years, appear to have found a way to survive some of their most destructive threats by attaching to and growing under mangrove roots.

Science has barely scratched the surface for zoanthid species

Researchers collecting zoanthids from the Indo-Pacific realized that we haven't even come close to discovering all the zoa species. At least 9 of the 24 species they collected are undescribed. Even more remarkable, when they reviewed 600+ zoanthids collected as far back as the 1930s, they discovered many have yet to be formally examined.

From curious aquarium inhabitant to intriguing biological model. Clownfish continue to inspire science. These charismatic fish have attracted attention for their vast diversity across the Indo-Pacific reefs. Understanding how so many species that span such a variety of shapes and colors have materialized has been an intriguing question worth exploring and understanding.

Public aquarium accidentally kills 100 reef fish with botched fluke treatment

When praziquantel reportedly failed to cure fish of flukes in their Atlantic Coral Reef exhibit, the staff at Albuquerque's BioPark Aquarium inadvertently killed about 100 fish - in front of patrons during operating hours - by using a more toxic and risky treatment, Dylox.

What is Dylox and praziquantel?

Dylox is the organophosphate, trichlorfon.  Trichlorfon is one of the active ingredients in many over-the-counter fluke/worm medications.  While it has been shown effective against monogenetic trematodes (flukes), some monogeneans have developed resistance to this organophosphate.  Dylox is also a  neurotoxin that can cause serious harm to animals including humans.  Fish exposed to high levels of Dylox (or old batches of Dylox) can exhibit nervous system and respiratory problems leading to death.  Even low dosages of Dylox can visibly stress fish.  For these reasons, it has fallen out of favor as a first-option fluke treatment.

On the other hand, praziquantel is extremely gentle on fish and rarely causes significant distress or death.  Overdosing with praziquantel almost requires willful intent because very large dosages are required to harm fish.  It's also proven to be a highly effective anti-trematode treatment for both freshwater and saltwater fish, although BioPark Aquarium staff reported praziquantel failed to cure their fish of flukes.

Learning from Tragedy

This unfortunate event reminds aquarists that when improperly administered, the cure can sometimes be worse than the disease.

  • Research your medication.  Know what medication is useful for what ailment, and just as importantly, which medication is best suited for the species of fish you intend to treat.  Some medications do not work well with specific fish (e.g. praziquantel and some loaches, copper and some angelfish).
  • Carefully calculate dosage.  Double and triple check your decimal points and conversions!
  • Have emergency water-change water on hand.
  • Do not mix medications unless you are absolutely certain there are no contraindication.
  • Never use old or expired medication. For example, old Dylox can be particular harmful to fish.
  • It is advisable to start treatment with the most proven, gentle medication first before advancing to more aggressive treatments as necessary.
  • Weigh the risks versus reward when using any harsh chemical treatments.

A silent guardian. A watchful protector. A pinchy armored knight. That's what Trapezia crabs are to corals. A new research details the complex symbiotic relationship between crustacean and their host cniderian. These little crabs may be a coral's best defense against predators like Crown of Thorns Starfish.
