Welcome to your new life as a fishkeeper! You’re now responsible for tiny, water-bound creatures who will never once thank you for feeding them or keeping their home clean. But hey, at least they won’t wake you up at 3 AM demanding food (looking at you, cats).
Starting your first aquarium should be exciting, not overwhelming. Whether you want a tiny, low-maintenance betta bowl or a full-fledged 29-gallon underwater metropolis, the options above have you covered.
So go ahead—set up your new tank, add some decorations, and watch your fish explore their new domain like tiny, judgmental submarines. And remember, no matter how much you want to, resist the urge to overfeed them. We know, we know—it’s hard. But trust us, they’ll be fine, and you’ll avoid turning your tank into a murky swamp.
Now, happy fishkeeping! May your water be clear, your filter be quiet, and your fish be forever unbothered.
