Another design that should work equally well for pelagic fry is Liisa Coit's "critter keeper" nursery. I know first hand that she has had good success with it. I believe you can find it in her photo album on photoisland.com.
Husbandry:
This is a well covered subject and I am certainly no expert so I will simply share with you my practices. I siphon detritus from each tank twice daily just before feeding. I wipe the bare bottoms clean when they need it and occasionally clean the front glass. I rarely clean the back or sides as they are covered with ‘pods and I feel that a moderate growth of algae is probably good for the system.
As previously mentioned, water changes are accomplished by the daily removal of water from cleaning and regular replenishment of the reservoir tank.
I feed all the seahorses twice daily at roughly 6–7 a.m. and 6–7 p.m. I would like to feed the fry more frequently but sadly, I have to work for a living so that is not possible. I culture and fortify bbs (artemia) as outlined in The Plankton Culture Manual and use both Selcon and LiquidLife as enrichment products. As soon as possible (about 8 weeks) I get the fry started on Hikari mysis but continue adding the bbs for several more weeks. As the fry grow I make the switch to PE mysis and that is what I feed the juveniles and adults.
Conclusion:
The above information is not the result of any long term effort or continued success. My horses just began breeding last June and I have only reared three broods. There was a fourth, actually the first brood, but I lost that to "operator error" if you know what I mean. I have been fortunate in that I have not had to deal with disease or any other disasters thus far, I’m sure there are still many hard lessons ahead. I wish I could say that this is THE way to go but only time will tell. At this point I have a 21% survival rate from the three broods at three, four and five months. That’s 42 happy, healthy and frisky seahorses! I now have another 275 fry and will try my best to bring them through.
