Thank you for the update. It’s good to hear that your lonely female has regained her appetite and seems to be feeling more like her old self again. The mirror trick usually has a positive affect on widowers and often helps to snap them out of their funk. It is comforting and reassuring for them to see their mirror image, which moves when they move and seems to respond to their actions. It makes them feel like they’re still in the presence of another seahorse and not all alone.
I agree, the next time you get a chance to visit Hawaii, you should definitely make a point of touring the Ocean Rider seahorse farm. That’s something that every seahorse keeper would find utterly fascinating, and I’m sure it would be one of the highlights of your trip.
Best wishes with all your fishes, Cathi!
