Does anyone have any links to scientific data or anecdotal evidence(this might be hard to quantify I assume) that aquatic or terrestrial plants negate Somatostatin(the hormone that regulates fish growth and metabolism)? I couldn’t really find any published experiments supporting his hypothesis that plants absorb somatostatin or are even reduced by plants alone, just a lot of “trust me bro” posts on aquarium forums. This conversation started with my close friend who’s a hobbyist as well and it’s regarding fish growth rates between our two systems for the same species.
