HI, I'm sorry for the delayed response.
I have a few questions to help u further than what I am going to post. Where did you get the seahorses? I assume a pair (m and f), were they captive bred or live? How big of a tank... what other tank mates and just tell me about them in general.
I recommend you reading the FOTW i wrote here a few months ago u can do a search for them under: FOTW SEAHORES...
Here is just the feeding segment of the article but I do recommend u read the rest:
FOODS!!!
This is a very important section. The most problems I hear about having with seahorses is with them not eating or people trying to convert wild caught to frozen. If a seahorse doesn’t want to eat something there is no simple solution. However, a good source of food would be tiny shrimp such as mysis, ghost, glass, red shrimp or sushi shrimp, baby mollies and guppies. If you are just trying to get your seahorse to eat something, try brine shrimp. Most of the time it will get them to eat SOMETHING, but is not at all healthy for the seahorse. Use brine shrimp as a last resort. It is said that brine shrimp to them is like cardboard to us.
Now in trying to train seahorses to eat frozen of other type of shrimp, I would recommend a few things. First, I would enrich the food with garlic. I would then mix up frozen and live food. For instance, I pour in mostly live food near some sort of current like the filter mixed with frozen food. All the food will look like it’s moving and may start to get the seahorse to eat the frozen. Another option is to set up a one-gallon bull and place the seahorse in there. Add the frozen from and eye drop so that it looks like it moves and mix up some live food.
As for trying to convert it to a different shrimp, there really shouldn’t be a problem at all. Brine shrimp is not what seahorse usually eats out in the wild but some seahorses will only eat that for some reason. In such a case I would recommend mixing up live brine and mysis or any other type of live foods. Once again, pour a lot of the food around the seahorse and watch. IF it comes to placing the seahorse in a bowl to get it to eat, do so. Sometimes isolation of the food will give the seahorse more time to eat.
In a case of this not working do not feed the seahorse for two to three days. Then, add whatever food you are trying to get it to eat. If it doesn’t take, feed the same food next day. If it doesn’t take than add the food it’s eating and then feed righteously for a few days and try over again. Soon, it will catch on that you are putting in food for it to eat.
