Curated starter supplies researched for this companion's specific anatomy and needs
Heavy power filter currents exhaust long-finned bettas and tear delicate caudal fins; gentle air sponge filters circulate water with zero fin pull.
Bettas breathe atmospheric air via their labyrinth organ; placing a resting leaf hammock 1 inch below the water surface lets them rest while breathing easily.
Tropical bettas kept in unheated bowls develop fin rot and lethargy; preset heaters maintain 78°F water to support active digestion and immune defenses.
