Not too long ago I bought 4 goldfish, mainly to amuse Paxton and the twins. I found one fish dead on the floor a few days later. I suspect my cat, but it might have jumped out of the fishbowl.
Of the remaining 3, two of them got really big, like more than double in size, so I went and got a small aquarium and an airstone. Paxton named his fish Quin, Landon named his Rocky, and Zoey named hers Elsa. Quin is the biggest, Rocky's isn't far behind, and Elsa isn't much larger than the day I bought them.
Anyway, even though they were only around $0.75 each, I'm experiencing buyer's remorse because, after getting them a tank, I've got to get (or make) a decent water filter and maybe a water-exchange system. Also, I put in 3 different live plants and they're doing really well, so now I think I should change the substrate - maybe put down a layer of clean sand, which I'll have to buy, and then the gravel.
And if everything keeps growing at the current rate, I'm gonna need a bigger tank
Although, you know, accidents
do happen. And fish don't live forever.
