Seeing as Glofish are Danios, the tank absolutely was not made specifically for them. It's just marketing.
I also would not just let the fish die. That's cruel after all. See if your local fish store will take them, or purchase a 10g tank. Most places have 10g's for $10.
I would also def write to the organization as suggested. Perhaps you can actually help them, help teachers. :)
130g: 7 Angelfish, 1 Bolivian, 12 Neon Tetras, 14 Serpae Tetras, 9 Kuhli Loaches, 1 Otocinslus, 1 Corydora ? Ghost Shrimp
I've noticed that people HATE it when you point out how stupid they are, so now I try to do it politely.
