oscars are like upscale goldfish. much smarter and much more funny. infact i think they should have a name swap with water dogs.
imean, for around 6 dollars + immortal tank cost, you get a good decade of fun like dogs for a fraction of the price even with meds. i think its a steal for a much more convenient equivalent to dogs.
and when that fateful time comes for your best buddy to mulch, you buy another baby and watch yourself become 10 years older! woohoo!
