I got a 45liter aquarium with like a dozen guppy
they have no plants, only plastic decoration, the water temp is kept at around 21C and there is a cascade aeration filter always running.
are water changes (2/3 of total) every 30 days too much? they have been like this for a few months, they look healthy and even keep birthing new fishe, so I know they can survive but I wonder if they're suffering/uncomfortable like this.
its not my aquarium, I clean that shit because otherwise they'd go without water changes/cleaning until the glass can't be seen through from the algae growth. I'd rather don't keep fish but I guess I can't leave them die either. Still doing water changes every week is a pain in the dick
