I have tried at just about every zoo for a photo of the sweet ever moving seahorse. I have failed several times. They are usually shown in dark aquarium buildings. And, did I say, they are EVER MOVING!! Even when "resting" sometimes hooked onto the flora with those tails, they are moving, swaying to and fro.
When we visited the Tampa Lowry Zoo I tried again. I took 13 photos, these two turned out the best I have done yet. Both photos have been sharpened during the editing process.
You can see this little fella (or gal) is clearly hooked onto the flora (not sure if that is real live flora or not):
