yeah, 4 yrs in a 29 gal... uhoh.. and then ??gone for a week?? and that's what was there when she got back??? I'm sure it looked wonderful before she left. And as if her being home was keeping it from whatever happened "while she was gone".... disgusting.
And she's coming to the store you work at? Is it a private store? Any way to deny her from getting more fish? by talking to the owner, etc?
