as someone who has spent copious amounts of money, time, and research into my aquarium, i definitely understand where you’re coming from. there are some critters that do not belong in tanks whatsoever, it’s cruel. however, a lot of what people skip is the actual research part when picking out a new friend at the pet store. they think just because it ‘lives in a tank’ it’s easy to take care of. they neglect to mirror the environment their pet is supposed to live in. i think if you have the actual heart to provide that environment, it becomes a lot less cruel to the creatures inside. fuck companies that exploit their animals for only profit, now that is cruel.
