My seahorses

[JSTR]

Watch all the stores here in Calgary - a few have had something other than H. kuda, but not often.
Easiest form of copepods to get is cyclop-eeze, just remember to pre soak it for at least an hour prior to feeding. dump th e cyclops-eeze directly into the flow so they appear to move.
If that doesn't work enriched brine shrimp are your last resort. Even large seahorses will eat them - remember they are not nutritious at all, so they must be enriched with good phytoplanton or products liek Selco.

The H. kuda you got are all from the same distributor in the Phillipines. Not 100% sure if wild caught or captive bred. By the way should you look into purchasing more of these - I would never spend more than $60 per horse on captivebred.
Saw those ones at the LFS, didn't look to healthy in their tank, better to leave them there. One easy give away is to check out the eyes if they are not cnstantly searching for food - something is wrong with the seahorse.
