So after all these years, we STILL haven't figured it out? That's so funny.

In FT2, description of Golden Seahorse says;
"This magical Creature increases your odds of selling fish!"
I wonder if same applies for first FT

"How does the seahorse work?

Once a long held mystical secret from the land of Isola, we have discovered the golden seahorse's fantastic power in Fish Tycoon 2. Owning the seahorse increases the likelihood of a customer purchasing a fish. The seahorse does not take up tank space."

Taken from the Research and Upgrades page of Last Day of Work's Fish Tycoon 2. Sounds legit. Sounds even more plausible when you take into account that Tanks 1 and 2 hold 20 fish but the Sell tank holds 21. Since we know that the Seahorse takes up 1 space, it makes sense. Almost like the developers were dropping us hints that the Seahorse works its magic in the Sell tank.

I've been playing Fish Tycoon for about 5 days now and added the Seahorse to Tank 1. Yesterday I began to notice some of the baby fish were born at age 2 days vs the usual 1 day. Since I've only noticed this in the 1st tank, is it safe to say the Seahorse ages some babies by 1 day? Also have Magic fish 1, 4, 3, 7, 2, in that order.
By curious nature, I'm wondering why the Seahorse ages if it has no purpose in breeding and apparently doesn't die, or can it die?

I found that when putting the seahorse in your selling tank and tapping on the customers to see their reactions in sell mode 1 out of 5 people or so show a heart with a fish in their thought bubble. When the seahorse is put back into tank 1 this becomes much more rare. However I don’t notice much if any of a difference in sales (Same species of fish sold with same price)

Upon further review it definitely makes the customers happier and increasing the rate at which they purchase. I don’t have a whole lot of ornaments in my tanks so I may notice it more than others. I picked up the app a few weeks ago and have been wondering what the seahorse does and thought it was quite strange when no one online knew what it did. I hate to take the mystery out of it though
