Not Dwarf Seahorses, Baby Seahorses

It came to my attention recently that sometimes very young juveniles of larger seahorse species are being sold as Dwarf Seahorses Hippocampus zosterae due to the exceptionally small size they are being sold at. This issue came to light by way of the our forum member Maryg. She asked to confirm the species of a couple seahorses sold through her local fish store as dwarf seahorses. The seahorses in question were in fact juvenile Tiger Tail Seahorses Hippocampus comes

Frozen Mysis Part 2: The Science Behind the Food

Photo by Louise Hines In Frozen Mysis Part 1: The Quest For Quality Mysis, we took a look at how to best select quality mysis for our seahorses, and what to avoid. In this long overdue part two, we’re going to take a look at why being picky about our frozen food matters. Just What Does Freezing Do

How To Pick Your First Seahorse: 12 Common Seahorse Species Explored

Any number of species of seahorses can be suitable for the right aquarium. Left to right: Hippocampus erectus, Hippocampus barbouri, Hippocampus reidi I’m often asked which species of seahorse aquarists should get for their first aquarium. This question may sound simple enough, but different species behave differently and have varying levels of care required. I’ve put together a list of the most commonly available species, their difficulty level and some additional notes.

Opinion: Selling Baby Seahorses Is Wrong

Seahorse baby being sold far to young in a listing on eBay. It happens every so often. Someone discovers just how easily seahorses breed, but can’t raise the babies, or discover the expense and time it takes to raise seahorses and so they decide they can sell the seahorse fry and make some money doing it. Unfortunately, it’s a mistake and it ends badly for everyone but the seller. To understand why selling seahorse fry is wrong, we need to look at what causes this situation. Seahorses breed extremely easily

Is Your Seahorse Floating? Seahorse Pouch Evac How To Video

Written By: Tami Weiss | Date Posted: 08/27/2014 | | Is your seahorse floating? Gas in the pouch of seahorses is one of the most common ailments of seahorses in captivity. Knowing how difficult pouch evacuations can be for seahorse aquarists, we put together a video that shows how to do a pouch evacuation on seahorses. Many thanks to Momo Yang and his master editing skills in getting this put together. This is the first in a series of how to videos to come here at Fusedjaw.com

Seahorses for all

Seahorse aquariumWhat was once the domain of public aquarists only is now widely available for all hobbyists.  Captive-bred seahorses and systems designed specifically for keeping and breeding seahorses will now be available form Reef Eden as from August. The SYNGNA system employs a Tunze circulation pump and baffles to convert high velocity water flow into a smooth mass volume water motion.  A Tunze skimmer and Cree XH-G and ML-E series 16k LEDs also come standard with the system. Whether you’d like to display them or breed them, as long as you have £1000, you can try your hand at it. Here are some more specs:… More:

Introducing the Snowshine Seahorses

Introducing H. erectus var. Snowshine. As the head seahorse nerd and proprietor of FusedJaw.com, most of my articles shy away from my own operations. However, I’ve had a project underway I’ve been quietly working on for while that I’m excited to share: The Snowshines, a new variety of Hippocampus erectus. This new variety of seahorses, named Snowshines in honor of both the blustery state they were created (Wisconsin) a well as their unique coloration. Snowshines are still Lined Seahorses, H. erectus, but through selective breeding exhibit an unusual amount of pearlescent white markings, mixed with a base coloration that can manage a wide range of colors, all tinted with a glistening sheen. Light colored Snowshine H. erectus There have been a few varieties of seahorses offered by breeders based on color; but seahorses can change colors, making breeding for color a daunting task. Pintos, pieds, and other piebald varieties are probably the most well known, bur aquarists are frequently disappointed in the finicky color changes that can obscure the prize markings. The trouble with trying to breed for color with seahorses has always been that they are masters of camouflage and change to match their surrounding. But there is no set formula to encourage seahorses to display specific colors. There are certain tricks one can do, such as offer brightly colored holdfasts, but no one technique reliably guarantees color. And no one is quite sure of the extent that color is even an inheritable trait, as seahorses, like octopuses, use chromatophores (color-changing cells) to blend into their environment. Comparing Snowshines to wild-type H. erectus. Left shows a normal wild-type H. erectus at the bottom, and Snowshine var H. erectus above. Right image shows a wild-type H. erectus in the foreground, and Snowshine H. erectus behind it. I’ve been pondering this problem for a while, and decided to approach it from a different direction. Instead of attempting to breed for the base colors, which change, I’ve been selecting for the white coloration that occurs in the saddles and stars. Saddles are white patches that occur on the dorsal side of many seahorses, and stars are the small white dots that appear on many seahorses skin when displaying dark coloration (sometimes confused with ich by novice aquarists.) My observation is that these markings and color are more ‘sticky’ than the wide range of other colors H. erectus can produce. In working on this, I also noticed these markings seem have a certain amount of pearlescent shine. “Saddles” highlighted in yellow, “Stars” highlighted in blue on a wild-type H. erectus. Photo courtesy of Brian Gratwicke Snowshines are the results of using those observations to selectively breed a variety of seahorse that shows these traits amplified. Saddles merge to create large blocks of shiny white coloration. Many of them have masks much like certain clownfish varieties. And while the base color can change; black, green, yellow, and orange, brown are all color combinations I’ve seen underneath the white. My favorite, however, is when they display white on white – they not only show the white patches, but white coloration underneath, while displaying dark horizontal lines characteristic of H. erectus. Just like all seahorses, their colors are flexible, but the pearlescent “shine” stays. For example, many aquarists tend to shy away from darker colored seahorses. But with Snowshines, a black seahorse becomes a dramatic contrast of brilliant white and stark black. And while the exact coloration, shape and appearance does still change as they age as it appears with all seahorses, they keep the most dramatic coloration, the shine. Snowshine brother and sister from two different broods. Large male is 13 months and small female is 5 months in photo. The idea in selecting for these seahorses is partially based on the widespread interest in Hippocampus zebra, a rare deepwater seahorse that has only been found a handful of times. I’ve often wondered why someone doesn’t try to selectively breed H. erectus coloration to imitate H. zebra. H. erectus which has bold lines, but the distinctions between the lines and background colors of H. erectus isn’t very impressive. Eventually the idea brewed in my head long enough, and that someone became me. I didn’t end up with exactly what I set out to create, but I think I’ve created something much more interesting. A white-on-white Snowshine seahorse with bold horizontal stripes H. erectus is known for. Snowshines will be available for the first time through Diver’s Den. For those of you not familiar with Diver’s Den, it’s LiveAquaria.com’s WYSIWYG (What You See Is What You Get) shop that let’s you purchase the exact fish or invertebrate you see photographed. If you’re interested in a truly unique seahorse, keep your eyes glued to Diver’s Den.
