I used to have a couple aquariums, one 40-gal brackish, under-cabinet canister filters, etc, etc. A fair amount of work, but what really started to get to me was the captured animal trade, which kills a lot of fish in the process of capturing and bringing them to market.
I decided if I ever keep an aquarium again, I'm going to stick to captive-bred, etc.
But this is a tricky hobby to start during isolation. :)
