Brief Biography:

I was always fascinated by fish and when my girlfriend was looking for a class pet for her third grade class (she is a teacher) we saw those aqua babies things at the local target.  She bought one and I wanted one but I wanted the bigger tank but the only thing that came in it was a frog.  I saw a nice looking tank with a dead frog so I got a discount.  I cleaned it out and went to PetCo to buy a small fish for it.  After feeling sorry for the fish I bought a larger 2 gallon tank with an undergravel filter and my addiction exploded from there.  For my birthday, my girlfriend bought me a complete 37 gallon acrylic aquarium, hood (Eclipse) and stand.  I learned about the biological cycle and added some hardy fish, most of them made it.  Not too long after, one of my fish (it was a freshwater) had babies and I learned how to care for them (they were Mollies).

After that, I started seeing other fish I liked, and I setup another tank at work for a spotted puffer (Puffy).  He was the office pet until I decided I wanted him at home so I moved my freshwater fish and put Puffy and more puffers in the 37 brackish tank.  I considered myself fairly successful and my knowledge grew a little and then I wanted a bigger challenge of a saltwater tank.  I started small, a 10 gallon with live sand, LR and I modified a Lee's protein skimmer to fit.  I had a hangon filter for mechanical filtration.  My first saltwater animals were damsels, one brown seahorse, a couple horseshoe crabs.  I have no idea how the seahorse survived after know what I know now but he was still the best seahorses I have had to date.  I lost the whole tank during a move to my new house.  Now that I am fairly settled again, I started by learning wild caught seahorses are not the way to go and that raising seahorse fry is the most challenging I have ever encountered with this hobby.  After doing a lot of reading on the .org site, I bought some fry and I am trying to raise them to adults.  My wild caught had 13 fry and I lost the remaining four to hydroids after almost 5 weeks.  I know the percentages are low but I had to try again and this is were we are now with my tanks.

Temperature Range for Our Seahorse:

  • 76 to 78 degrees F, although during warmer days the air conditioner is running and maintains 78 degrees F.  Before turning the air conditioner on, I saw it reach 80 and since then left the air conditioner running to keep the tanks cooler.

Acclimatization Process:

  • The way I did it was probably not "by the book" but since I knew where the seahorses came from I assumed it was ok.  They sat in a bag of tank water of about an hour to equalize the temperature, I opened the bag and allowed the bag to sink under the surface of the water and let the seahorses swim out on their own.  I removed the bag with the water in it.  They took anywhere from 15 mins to an hour to swim out on their own.  I would not do this if I received them from the LFS and I did a thorough inspection of the bag before doing so.

Additional Comments:
 

This is my first attempt at raising seahorse fry in a fully established small aquarium.  I had used a bowl for my first small batch of 13 premature fry (father died giving birth) and I thought I would try again by purchasing fry from seahorse.org members and try raising them in a stress free (from water changes) environment.  The results are still yet to be seen.
