Breeding Question

    Pete, a couple of weeks ago (don\’t know if you remember), but I had e-mailed you to see about my pregnant male. He had released only unfertilized eggs after 15 days and apparently that was all he had. It\’s been almost a month since then, and he doesn\’t even seem to have an interest in breeding. Is this something I should be concerned about?

    Dear Sean:

    Yes, sir, I remember that incident very well. As long as the male that expelled the unfertilized ova from his brood pouch hasn’t developed a problem with positive buoyancy, then I don’t think he will suffer any repercussions as a result of the aborted pregnancy. Pouch bloat can result from gas produced by the decay of embryonic material and the remains of placental tissue or other organic matter (possibly even stillborn young) within the brood pouch, if the male is unable to flush it out and cleanse it properly by pumping water in and out during its pouch displays (Cozzi-Schmarr, per. com.). That hasn’t happened with your male, indicating that he was able to resorb any fetal fry or embryonic young that may have remained despite the complications that arose during his pregnancy. It’s unfortunate that he was unable to carry any of the fertile eggs that implanted to full term, but since he was able to successfully eject the unfertilized that failed to implant, I think he should be fine and none the worse for wear as a result of this experience.

    I wouldn’t expect him to show any interest in breeding after this episode. Once a female has released her clutch of eggs, she will not produce more ripe ova until their next breeding cycle, which would be about a month in the case of Mustangs and Sunbursts (Hippocampus erectus). In other words, his mate has been incapable of mating for the past several weeks, which may account for the lack of activity in that department. Now that it has been nearly a month since their abortive mating attempt, you may see your mated pair getting down to business again.

    Remember the factors that influence gestation by affecting the levels of key hormones we discussed after your male expelled the undeveloped eggs, Sean? We talked about how low oxygen levels, dietary deficiencies, heat stress and other aquarium stressors can influence hormonal secretions and disrupt the pregnancy or prevent seahorses from breeding successfully. Just be patient, provide your seahorses with a nutritious diet, optimal water quality, and a stress-free environment at all times, and sooner or later they will do what comes naturally.

    Best wishes with all your fishes, sir! Here’s hoping your seahorses breed again very soon and produce a healthy brood of young this time.

    Respectfully,
    Pete Giwojna

    Pete, thanks for the response 🙂

    Yes sir, I remember the advise you gave me very well on the factors that influence gestation. I took the advice to heart and made them the best habitat possible.
    I have the chiller, so it is a perfect 74 degrees constantly. I increased my water turnover to approx 6- 6 1/2 times per hour by upgrading to a larger skimmer and raising the height of my canister filter to reduce the head pressure. I also now have a power compact lighting system that has a dusk to dawn feature with moonlights all hooked to separate timers and it is working perfectly. The male shows no sign of having buoyancy problem’s, and in fact is quite playful.
    Their tank is right next to my desk- where I spend most of my time (gotta pay for them somehow:) and they spend all day dancing back and forth changing colors trying to get me to feed them. I check my water parameters daily and hopefully all will be well in the future.

    Thanks for all the advice,

    Sean

    Dear Sean:

    Excellent! A stable water temperature of 74°F is perfect for Mustangs and Sunbursts, and the turnover rate for your seahorse tank is right where I like to see it — very good circulation without being overpowering. The new lighting system to provide a simulated dusk and dawn is outstanding and the seahorses sound like they are happy and contented. All of which should help assure that they have a healthy interest in courtship and breeding. Well done!

    Best wishes with all your fishes, sir!

    Happy Trails!
