Sorry I've had a busy few weeks, so I just am first getting a chance to catch up now.
Sure, I can do that! I'd also love to hear from all of you how you're keeping your seahorses. I wonder what differences are between how we keep seahorses in the US and how they are kept there.
I recorded a quick video to show how I currently raise baby seahorses.
It's not an ideal setup, but it works. I have plans of building a shared system which will reduce the amount of labor, but until it gets done, this is what I will continue to use.
As for tips, off the top of my head:
Minimum 30 gallons for most species (114 liters)
Keeping seahorses at cooler temperatures helps combat bacterial infections. In general, tropical species are kept between 70-74F (21-23C).
Frozen (thawed) mysis shrimp is the staple diet, but variety is encouraged, including small krill, live amphipods, and enriched brine shrimp
Higher flow rate is recommended these days; seahorses do better with a turnover of 10-20times/hour the overall tank volume. Some people do even higher, though I haven't experimented with that.
For babies
Enriched artemia nauplii is the only artemia that should be fed.
What you enrich with is very important. You want something that is high in DHA. Here, that's algamac-3050, or Dan's Feed.
A lot of species can't take baby brine shrimp from birth because the food is too big. Rotifers are the right size, but they don't move "right" for seahorses, so they aren't a great choice. A pelagic copepod that is small enough is ideal.
bacteria can overwhelm babies, so its important to keep the rearing tank clean, including wiping away any biofilm (films of bacteria and algae) that accumulate.
A some seahorse breeders are starting to use blue round tubs to grow baby seahorses: http://www.fusedjaw.com/breeding/seahorse-fry-system-build/
I will add more as I think of them.
