[ oh god... that would be the coming of the next fish-pocalypse! but he looks at the tank too, as if staring at it will help him generate ideas. there are probably bigger tanks out there, in the realm of the pet shop! they just have to look... ]

Like, you know how hamsters and mice have obstacle courses? What if we got one custom-built? Mikazuki probably has enough credits to afford everything we need, so money won't be an issue.

[ yes..... tsuru loves to put things on mikazuki's tab... but the biggest purchases that he slaps on mikazuki's tab are never for himself? they're always gifts for others, and now gifts for fishy! truly, he has a good heart. ]

If we could somehow turn that spare room into an aquarium, it'd be nice. Or if that's too much work, we could just fit a reaaaally big tank in there.
