Allow me to ask a few ?s plz. As I just added some Pothos to help remove Nitrates & Phosphates from water.

1st Will pothos survive totally submerged or do I have to keep it above the waterline?

2nd Can or will it hurt any of my livestock listed below?

I know I can use a HOB but would rather to keep it fully submerged if at all possible.
Tank Setup - 135gal, fx5, mag350, korilla 4, 3 silver dollars, 3 Red blood parrots, 12" Green severum, 10 coreys (3 emerald & 7 swarts), 2 black spotted eels, 22" fire eel, 24" clown knife, sun catfish, and leopard plaeco
