Me Christian Believer and I still keep fish, had been doing this
since young age, now scaled down alot cause no time to take care of
them.
Personally I would like to keep an arowana, but realised that I do
not have that much of time to take care of it, so now keeping only
Goldfish.
In principle, there is nothing spiritual about keeping arowana,
like my late mother used to says, good also one sentance, bad also
one sentance, its all depends on the speaker's perspective.
So to keep or not to keep the fish, its entirely up to your own
perspective of it.
By the way my daughter when she was young, also keep saying that
she sees another girl in her room, and she keep telling us to chase
her away, later we realised that she was imagining Goldilock (the
one from the story of three bears) had managed to breakinto our
house and eat her food, play with her toys. so for your daughter
maybe a good talk with her is needed.
