....more than other similar size fish? The bioload is mainly, if not entirely based on the amount of food you put into the tank, correct? Goldfish can't just create extra waste out of thin air. It all has to come from the amount of food you feed.

not quite, it comes from how an animal processes the food it eats as well as the type of food it eats.

the primary natural diet of gold fish is greens, (goldfish will decimate a planted tank and actually do best if given leafy greens and veggies like peas to supliment their diet)
the primary diet of most other fish is actually protein...aka...insects and other...smaller fish...
(this is why theres different foods for goldfish and tropical fish....)

vegetable matter and protein matter are processed by the body differently (no matter what species or how well adapted that body is)
veggie based diets are much higher in fiber typically producing much more undigestable mater passing through the gut than their carnivourous counterparts.


plus goldfish are messy eaters, often missing half the feed fed so you add decomposing/missed food mater to the equation and you have a fish that puts a higher strain on bioload.

then we take into account that bioload is SUPPOSED to be calculated on the fishes estimated ADULT size (not current size)...
even a round bodied fancy goldfish can reach 12 inches...
putting a much higher strain on a tank than a fish whos 3" when mature...

I feed only pellets and flakes to my fish and only small amount that they can consume within seconds with very little waste. Anything that dropped to the floor will be eaten by them later. I feed them daily. I don't see the goldfish's bioload any more or less than the biolaod from my guppies, considering the even mass of the two. Meaning, comparing equal amount of weight of each type (say 4 guppies = 1 small goldfish).

I think it all has more to do with how much you feed, how you feed them, how much fish you have, and not so much with the type of fish. If I feed one ounce of food to guppies, they will produce one ounce of waste, and the same goes to goldfish.

firstly, most fish cannot eat off the bottom of the tank, their mouth shape isn't designed for it.

secondly unless you have a tank with NO substrate (meaning just an empty tank, no gravel, sand, dirt, plants, rocks ect, even those fish designed to feed off the bottom cannot remove every ounce of missed food, you would have to gravel vacume thoroughly after every meal to remove the detritus missed by the fish...

thirdly, just because you THINK something might be true...doesn't mean it is...you thought rams were bigger than mollies but ive already proven mollies will easily outgrow a ram...
people thought the earth was flat, but we all know that too has been disproven...

fourthly....if feed 1 ounce of lettuce to a person and 1 ounce of steak to someone else, the amount of waste each item leaves in the body will e different because of how the body digests diferent matter...
the lettuce has more undigestable fiber and thus would produce MORE waste than the steak which can be easily broken down by the body into a much more efficient product leaving less waste to remove form the system...
goldfish should be eating "lettuce" (a diet primarily made of plant matter) guppies should be eating "steak" or a diet made primarily of protein (typically insect based, youll noice they are surface dwelling with upturned mouths.)

im not entirely sure HOW you are seeing your fishes bioload, do you sit and watch them 24/7 to count how many times they go poop? do you have magical fishy vision so you can see fishy urine and count every time they pee too?
does that magical fishy poop/pee vision also give you some magical ability to somehow measure it every time so you can take the average from each fish?
no?
ohhh...because actual scientists HAVE done such thigns (by keeping individual fish of similar sizes in tanks alone with presicely measured amounts of water and presciely measured water parameters, (using something called a water test kit, something, if I remember rightly...you don't have time nor need for...) parameters which are checked multiple times every day to measure the average waste output of certain fish in certain environments...and yes it has been proven, inch for inch the average goldfish produces MORE ammonia per inch than any other fish...

so yes, 4" of goldfish WILL still produce MORE waste than 4" of guppies...despite what your magical fishy pee vision mght have you belive.

but you keep asking questions you don't actualy want an answer to so you can pretend to know better...while advanced hobbiests all laugh and roll their eyes if it makes you feel better... k ducky?!
