sorry
and for the 10G, even if ur attached to the molly fry, just sex them, and keep a trio(male + 2 females) and give away the others or just let them fight for survival in ur 26G.
for tetras
u could do 6-8 green neon tetras, they are super tiny and look great
oh dearz ._. my flying fox is actually the 'misidentified Garra cambodgiensis.' Oh dear, that had literally opened a billion more problems
