From the pages of the local aquarium society newsletter:
" In one of the shops selling a lot of plastic novelty and souvenier items, they are selling small plastic necklace globes, filled with coloured water and in each is a small baby fish, possibly a mollie or platy. Each globe would hold approximately 2-3 ounces of water. These are specifically aimed at the younger generation. Although each necklace comes with a set of instructions, including leaving a small air-space on top, feeding them everyday, and changing the water, and adding coloured vegetable dye, the instructions are not complete enough regarding temperature and the use of tap water. We are not only horrified at this as members of the hobby and Society, but also horrified at this practice of needless cruelty."
This all took place at Knott's Berry Farm......in August 1971 (putting fish in teeny, tiny containers is nothing new).
