Thanks for the link. Assuming the one person who posted said "The seahorse supposedly extends the life of the fish roughly 50 game years" or something like that, is right, then the seahorse has no use to me because my environment is fully researched. Then again the seahorse might be the reason I have never had a fish die, and have had only 1 disease.
They should put "Installs into current tank" instead of "Comes fully installed" because really, the seahorse installs into current tank.
