If you look up confused in the dictionary that decribes me. Last night my male\’s pouch was full and now it is not. I searched the filters and took them apart but nothing. I stirred up the gravel, still nothing. Were are those fry? WHAT IN THE WORLD HAPPENED?!?
ahhhhhhhhhhhhhhhhhh!!!!!!!!
November 23, 2006 at 4:06 am #3089Pete GiwojnaGuestDear Nigel:
Do you have any tankmates in with your seahorses that could have accounted for the missing fry? Cleaner shrimp or a wrasse or other fish with a mouth large enough to swallow the newborns? Pregnant males often give birth in the early morning hours, and if the seahorse tank includes any specimens that might have predatory tendencies towards the fry, they can easily polish of the entire brood by the time you get home from work.
If not — if there are no cleaner shrimp or other tankmates that may have disposed of the newborns — it may be that your male was only performing pouch displays (i.e., Ballooning or Pumping) the night before when its’ pouch appeared so distended. In other words, it could be that your male’s pouch was inflated with water as part of his courtship displays, rather than being turgid with a brood of developing young.
Either way — if your male gave birth overnight and the newborns were consumed by its tankmates and/or your filters, or if he was merely performing pouch displays for the benefit of your female — chances are very good he will be mating soon providing the female is receptive.
Best of luck with your seahorses, Nigel! One way or another, here’s hoping you have a brood of babies before you know it!
Respectfully,
Pete GiwojnaNovember 23, 2006 at 6:58 pm #3091nigelseahorseGuestOnly 2 snails are in there. I rinsed out the filter pads. But what confuses me is that his pouch had been full for 2 weeks. Oh well. They are still courting and are bound to have babies one way or another.Plus during the next month or 2 I’ll get the a bigger home, 30 gallons. I resently discoved that my 20 gallon setup is accualy 15 gallons, ooops!
November 23, 2006 at 7:46 pm #3092nigelseahorseGuestQuestion: If a male gives birth in a reef tank can the corals (gorginian) eat the babies?
November 24, 2006 at 5:52 am #3093Saint2966GuestI am not sure I’d blame the Gorgonians, But when I ended up with only six fry outta my litter, I later found a few in the filter pads. I definately blamed an echinophyilla with 7 mouths sitting right below the filter flow. I have witnessed him with shrimp and calamari pcs. much larger than fry hanging out of every mouth. I also have a Lobophyillia Brain with a verocious appetite for small inverts. If you wanna raise babies you definately gotta watch any coral with mouths, or feeding tentacles:ohmy:
November 24, 2006 at 8:24 pm #3099nigelseahorseGuestI don’t have coral in that tank yet, but to be on the safe side I guess I’ll just use artificial coral. Hope you all had a delicious turkey yesterday!
November 25, 2006 at 2:51 am #3100trulyshyGuestHey guys,
I have a gorgonian in my tank with my seahorses and when the fry were born, the gorgonian didn’t do anything. I don’t think it would have anything to do wiht the missing fry…
Sorry to hear that they went misisng 🙁

Some live corals could indeed pose a risk of predation to newborn seahorses, but gorgonia should not be a problem in that regard. It is generally just the corals with potent nematocysts and large fleshy polyps that can be harmful to seahorse fry.
Soft corals have very little stinging ability and are generally safe for seahorses, including the newborns This includes most mushroom anemones (corallimorpharians). However, as Charles Delbeek cautions, "One notable exception is the elephant ear mushroom anemone (Amplexidiscus fenestrafer). This animal is an active feeder on small fish and will envelope them whole with its mantle then slowly digest them by extruding its digestive filaments into the space created. No small fish are safe with these animals in the tank (Delbeek, Oct. 2001)."
The hard or stony corals fall into two categories depending on the size of their polyps. The small polyped stony (SPS) corals have tiny polyps that extend out of minute openings in the stony skeleton, and generally have weak stings that should not pose a threat to seahorses. Depending on conditions in the tank, SPS corals such as Acropora, Montipora, Pocillipora, Porities, Seriatopora and Stylophora should be okay with fry and juvenile seahorses.
The large polyped stony (LPS) corals, however, could certainly pose a danger to the newborns. These include genera such as Catalaphyllia, Cynarina, Euphyllia and Trachyphyllia that have large fleshy polyps which often have tentacles equipped with powerful stinging cells. The Euphyllia and Catalaphyllia have the most powerful nematocysts among the LPS corals, and can deliver stings that are stronger than most anemones (Delbeek, Oct. 2001).
And of course anemones of all kinds, including Aiptasia rock anemones, and hydroids can take a heavy toll on seahorse fry.
But a gorgonian ordinarily would not be a cause for concern.
Best of luck with your seahorses and their future progeny, Nigel!
Happy Trails!
