Golden Guppy is right. And your Pink Stickfish will
die sooner or later. because They die of Old age
and You need money to cure him when he's sick.
or he'll die but magic fish dont die of old age just gotta cure em

And dont gemme wrong your fish'll die

Well they will not die if all your research is completed. They will die of old age if all you have is level two of fish environment.
