Hi, guys! Everyone knows I have dabbled in seahorses for a few years. I have tried a few spp, got a few up through a few generations, and now I am starting again with hopefully a more dedicated attempt. I had decided like a year ago to go with this spp because there is a way to get wildcaught. I have some wc, some cb and some net penned. This attempt has me baffled though. All these years I had thought all you had to do was put a male and a female together and you will get fry in 2 weeks. Not so, this time. And, I in my real research, I think I might have figured out why this time is different. I have had many more males than females. It turns out, in their native environment, that is bassackwards. In the ocean, seahorses are pretty solitary, and don't live in groups like I have. And, females are ready to spawn a little less frequently than males. So, my feales have been over whelmed by testosterone! They are always hiding! So, I am divying them up. I placed 4 female juveniles in a monoculture tank, a 20H with 2 wc males, ready as soon as the females are. In the display, I have my 2 other females with one male. The other males, the pipes and everything else is going to the one day cuttle. Wish me luck? I am going to use this thread to collect all my actual research info. |

Hippocampus erectus (Perry 1810) Order Gasterosteiformes / Family Syngnathidae Synonyms : H. tetragonous (Mitchill 1814);H. hudsonius (DeKay 1842); H. punctulatus (Guichenot 1853); H. fascicularis (Kaup 1856); H. marginalis (Kaup 1856); H. laevicaudatus (Kaup 1856); H. villosus (Günther 1880); H. stylifer Common names Lined seahorse; northern seahorse (U.S.A.); hippocampe rayé (French); caballito de mar (Spanish; Mexico) CITES Appendix II The IUCN (2003), considers the worldwide population of H. erectus as vulnerable, based on inferred declines of at least 30% caused by targeted catch, incidental capture, and habitat degradation.

Habitat Distribution: From Nova Scotia and Georges Bank (Canada) to Argentina, including the Gulf of Mexico and the Caribbean. H.erectus is the most abundant (hippocampus)species in the Gulf of Mexico and the Caribbean Sea. Found among seagrass, sponges, floating Sargassum in shallow depths. Salinity: It is uncommon in low-salinity waters. Nonetheless, Spring and Woodburn (1960) found it in waters with salinity between 21 and 34% near Tampa, Florida. Temperature: *****need to find temp and salinity in Gulf o Mexico*****near shore lines in shallow grass beds**** Edited by Suzy, Mar 6 2010, 09:08:55 AM.

| How do you make sure you are getting the same species? Is that a dumb question? |

No, it is not a dumb question. There are lot's of species that look really similar, and because it is not based on color like other fish, there are quite a few that I have seen mislabeled in my local fish stores. H erectus has a few strong characteristics, one being a broad chest. But, if you want to be truly scientific, you count the spines down their back, all the way to the tail. Different spp have different numbers... I have a printout saved from Project Seahorse ( Amanda Vincent is my fish hero!) that can ID seahorses. The hobby has really messed with the Seahorse! Ocean Rider (one of my favorite company based breeders!) over a few generations cultivated what they tried to promote as "Mustangs", "Sunbursts", and a few other cutsey names. But, they were all the same spp. People would pay extra ( a lot extra) for fish that would be a sweet shade of bronze... Edited by Suzy, Mar 6 2010, 08:11:25 AM.

That's always a good question, and something that we have talked a lot about in the class we are taking. Apparently, even corals that may look exactly alike can be different enough that they are not compatible, so you have to do your research. You should ask when you purchase them where they came from (what part of the world). And in the case of say, peppermint shrimp, if you want the ones that eat aiptasia, you should learn to distinguish the Lysmata wurdemanni from the other 5 species of peppermint shrimp. I guess the thing we have been taught more than anything is research, research, research...wouldn't you agree, Suzy? |

| Yes, but research in the right areas. No more researching RC for me! |

From NOAA: Adults are known from the surface and bottom waters of shallow and deep areas of channels, bays and saltmarshes, and along beaches and nearshore coastal waters (Hardy 1978; Wenner and Sedberry 1989; Froese and Pauly 2004). They have been found associated with oyster beds and weed-covered banks. Lined seahorses are usually associated with, or clinging to, aquatic vegetation such as turtlegrass (Thalassia), eelgrass (Zoostera) and Gulfweed (Sargassum). They can also be found clinging to soft corals (gorgonians). They have been found offshore to depths of 70 m (230 feet) associated with soft corals and benthic algae (Gilligan 1989). They tolerate a wide range of salinities (10.0 to 36.6 ppt) and temperatures (5.0 to 29.9°C; 41-96°F). Larvae are hatched from the egg in the brood pouch of males and "newborn" juveniles swim near the surface (Hardy 1978; Froese and Pauly 2004). |

Wow, 70m deep? That's interesting. That means they can handle cooler temperatures, rapid temperature changes and low O2 levels. Where are you doing your research right now? I still haven't found a great place online. Have you made it up to the U yet? Maybe tomorrow for me. |
