Target is promoting harmful pet products and misleading consumers. The 0.5 gallon Nature's Aquaponic by Penn-Plax is not a "healthy environment" for betta fish.

There's no space for bettas to swim, nor is there room for a filter and heater. Toxins accumulate rapidly in the low water volume, but the marketing of this tank gives people the (wrong) impression that the plants alone will sufficiently filter the water.

Will Target discontinue its sale of under one gallon betta fish tanks?

Target currently lists four under one gallon tanks on its website (all by Penn-Plax): 0.5 gal Nature's Aquaponic, 0.7 gal 3-1 Betta kit, 0.7 gal SpongeBob kit, and 0.7 gal Finding Dory kit.
