Hard water comfort
Platies prefer consistent mineral content; wild swings toward RO-soft water can cause shimmying or clamped fins. If your tap is soft, remineralise deliberately rather than hoping crushed shells catch up eventually.
Vegetable ration
Herbivore-lean livebearers benefit from algae grazing opportunities and measured plant feeding so protein-rich flakes do not dominate every meal.
