So, when are you going to give us the answers?
Ahah, it’s not easy like that. I’ll wait for someone to chime in. If noone answers I’ll leave you all questioning. Or you can google them

You’re just thinking too much about it now
There’s a tip on the (edit) riddle!
Alriiiighhht!
Any more takers?
5 fishes are left alive if you don’t consider “away” as out of the counting… Are dying and drowning the same thing? Do you include the dead in the count of whose left? Very confusing over simplification.
Where would they swim away if there’s no water out of the tank?
It’s the first time I hear that fish can drown in the water… Something “fishy” about that one Minnii !
