Coming Soon to Aquariumania - Episode 53: Diving into Aquatic Beetles with Dr. Jiri Hulcr

Aquariumania listeners-  Keep a look out, this episode is coming soon!

When you think of an aquarium, you don’t usually think of aquatic beetles. Dr. Jiri Hulcr, Assistant Professor of Forest Entomology at the University of Florida, and long time aquatic beetle hobbyist, however, thinks people have things all wrong.  He says that beetles are much more interesting than fish!   

So why is a forest insect expert such a big bug lover?  Dr. Hulcr explains where his love of "wet bugs" comes from, and will discuss some of the amazing biology and ecology of aquatic beetles that can be kept in aquaria, including the following species:

In the Family Dytiscidae

Cybister – common in the Southern US – easy to keep and impressive.

Dytiscus – common in more northern latitudes. Big, beautiful. The most beautiful larva.

Thermonectus – common in the south, but most species are note very interesting. 

Thermonectus marmoratus from Arizona is cool.

In the Family  Hydrophilidae

Water scavenger beetle:  

Hydrophilus – huge, pig.

Tropisternus – super common, kind of frantic.

After you download/stream and listen to the episode, and/or if you want any more information on aquatic beetles RIGHT NOW (!), feel free to contact Dr. Hulcr at: 

And check out some of Dr. Hulcr's cool aquatic beetle photographs:

Episode 36: Angelic Mysteries: Unlocking the Secrets of Angelfish Species and Varieties

This podcast episode delves into some of the "mysteries" of angelfish species and genetics. There are so many established and new varieties of angelfish, all beautiful in their own right, it can be difficult to keep track of them all! And beyond appearance, for you "CSI" types, what makes an angelfish "blushing" or "veiled" at the genetic level? Matt Pedersen, Senior Editor of AMAZONAS and CORAL Magazine, and Associate Publisher with their parent company, Reef To Rainforest Media, LLC, discusses these "mysteries" with us. His article in the most recent issue of AMAZONAS goes into more detail, but this podcast is a great primer! Here are some angelfish pics courtesy of Matt Pedersen, to whet your appetite:

Aquariumania Musings--Dec 18, 2012


Thanks for all your interest, and hopefully you are enjoying the most recent podcasts of Aquariumania at . Our next podcast will focus on freshwater angelfish--so keep an eye out for it, and follow us!

I wanted to update you on some interesting goings-on here at the University of Florida's Tropical Aquaculture Laboratory and beyond. . . . .

1. Some of you may have listened to "Episode 34: Banggai Cardinalfish Adventures with Journalist Ret Talbot" and learned about the work being done with the Banggai cardinalfish.  Well, the troops involved are getting closer to finalizing our information and we hope to have the "Banggai Rescue" book available sometime within the next few months next year, so stay tuned.  The Banggai Rescue project has been a fascinating adventure, and hopefully our findings will help spark renewed interest in this remarkable species.  Go to: for the latest information.

2. The "Rising Tide Conservation Initiative" spearheaded by SeaWorld-Busch Gardens Foundation ( is still going strong, with the help of our numerous academic, industry, AZA, and other partners. As research into breeding these more challenging marine aquarium species--to help increase sustainable options for the hobby and industry--continues, we will have our first graduate student joining the team to begin work on butterflyfish.  Stay tuned to Dr. Matt Wittenrich's blog at: and become a follower!

3. Although I am an aquatic veterinarian, I did start my journey in veterinary school with a great group of colleagues who shared a common love for helping maintain the health of animals, people, and our environment. Three friends and I recently published a novel inspired by our time in veterinary school--where we had to learn everything about all animals--dogs, cats, horses, cows, pigs, sheep, goats, chickens, and for many of us with "wilder" interests, many exotic terrestrial and aquatic animals as well!  
An Animal Life: The Beginning is a scientific medical mystery (animals and people are dying) and a quest for True Love (with a real cowboy) that unfolds as newbie first-year students struggle to survive the academic gauntlet of veterinary school.  If you love animals and ever wondered about going to vet school, here’s your chance to experience the joys and challenges without being kicked, scratched or bitten and at 0.00001% the cost of tuition. Go to: to find out more about our book and our lives as students!  The book is also available as an ePub.  Enjoy!

More to come. . . . .

Episode 25: Matt Wittenrich’s Psychedelic Approaches to Mandarin Goby Breeding

For many years, marine aquarium fish were only available from the wild. Then, in the 1970s, pioneering scientists developed methods for commercial production of clownfish. Over the years, other species including neon gobies, dottybacks, and seahorses also became available from fish farms. Most recently Dr. Matt Wittenrich “cracked the breeding code” for the mandarin goby, one of the more popular marine fish species. Dr. Matt is a well-known marine biologist, a highly sought after speaker, a nature photographer, and the author of The Complete Illustrated Breeder’s Guide to Marine Aquarium Fishes.  Matt recently earned his PhD at Florida Institute of Technology studying how larval reef fish feed. Join us, as Matt shares his psychedelic approach to breeding mandarin gobies.

Episode 15 - Killifish: Small, Secret Gems of the Aquarium World

Killifish are beautiful, small-bodied fish found in many areas around the world, including in the Americas, Africa, Asia, and Europe. They are, as a group, one of the aquarium industry's hidden gems. 

In Episode 15, we speak with Charlie Nunziata, a killifish expert who has been an active aquarium hobbyist for more than 45 years. Charlie is a life-long member of the American Killifish Association, through which he has been awarded numerous honors. If you haven't listened to Episode 15 yet, be sure to do it asap!

Here are some pictures of beautiful killifish of all ages!
