Over the years I've become increasingly against home aquariums for fish that grow bigger. I recently saw a fish that had lived alone in an aquarium die. It was horrible. This fish had lived alone for the amusement of the few people who actually even bothered to notice it. It swum around a background, plastic made-for-aquarium sea weeds and fake castles and such, and awaited feeding. I would walk by and go eye to eye with it and sometimes move my fingers as if they were fins and the fish would follow.
I heard that this fish had been in the tank for ELEVEN YEARS and was ALONE because he "ATE ALL THE OTHER FISH IN THE TANK." Well in the sea, fish eat fish, but I wondered if perhaps this was because he had not been fed properly.... And was also in a tank TOO SMALL FOR HIM.
HIM ... it could have been a HER.
The fish started laying low to the bottom of the tank, barely upright.
It's eyes were covered in some sort of white film.
I immediately informed the owner I thought the fish was dying and to contact their aquarium service.
A week later the fish was clearly having trouble fish-breathing, it's gills working hard.
I had not seen air being pumped into the tank.
The walls of the tank had a green-black film on them.
As a result I'm clearly anti-aquarium tank.
Perhaps the small fish that never get too big can have a better tank life than this?
Other fish in the tank.
Real sea weed.
Proper cleaning and feeding and light cycles....
