Opinion by Matt Pedersen
We just shared the news of the first successful captive-breeding of Hippocampus bargibanti at the wet hands of Steinhart aquarists Matt Wandell and Richard Ross. Marine breeders, and more specifically seahorse propagators, are no doubt ecstatic (Dare I borrow a line from from Ross: “Their heads are falling off”).
Of course, why didn’t this happen until now, and why can’t we all rush out to buy a captive-bredBargibant’s Seahorse? More »

Matt Wandell and Richard Ross are two professional aquarists who need no introduction to serious marine aquarium audiences. This dynamic duo of public aquarists has the kind of job most all of us would gladly commit manslaughter to have, working for the Stienhart Aquarium at the California Academy of Sciences. Wandell and Ross get to work on the type of aquarium systems most of us can only dream of and certainly will never afford. As if that wasn’t enough, they get to galavant around the globe on expeditions looking for new and interesting animals and husbandry challenges that many of us will never have the opportunity to tackle - like keeping and breedingHippocampus bargibanti, Bargibant’s Pygmy Seahorse. Can you smell, can you taste, the envy? More »

10 day old baby Pygmy Seahorse hunting copepods
For the past three weeks, Richard Ross has been spending his mornings next to a small tank in a back room at the Steinhart Aquarium in San Francisco. He leans in close. Not only is the room dark, but the fish inside this tank are masters of hiding in plain sight. They are Bargibant’s pygmy sea horses, and their orange, studded bodies twitch and sway just like the piece of coral they’ve wrapped their tiny, tiny tails around.
They are the first pair of pygmy sea horses to ever see the inside of an aquarium, and Ross is the first biologist to watch their daily pair bonding in a controlled environment.
As the lights slowly turn on, Ross can see that the two fish, each barely an inch long, are facing each other and twitching in unison. They rub snouts and butt heads. This ritual is part of their mating cycle, which culminates every 14 days with the birth of 60 to 70 babies. Immediately afterward, the pair detach from their pieces of coral, wrap their tails tightly, and the female deposits her eggs into the male’s belly sac, where he’ll fertilize and incubate the clutch.
Sea horse researchers call this the copulatory rise. ”The whole thing is very awkward,” says Matt Wandell, Ross’ colleague at the Steinhart Aquarium. On June 22nd, Ross and Wandell expect the pair to give birth for the third time since they arrived at the aquarium on May 20th. More »
