Highest and lowest waste producers

Hi,

What types of fish are the most and least waste producers?
I know that plecos are well known mass waste makers, also balloon mollys.
And tetras are among the less wasters. What others?
Thanks.

 

goldfish put out a lot of waste.

 

goldfish and guppies produce heavy wastes. angels r among least waste producers.

 

guppies are huge waste producers? I thought they were average/low?

 

I think guppies produce a lot more wastes for a fish that small , tha's just my opinion ;D.

 

My Mollys and Platys eat a ton and therefor produce a lot of waste. I hear plecos are big waste producers and I know that ottos and tetras are low waste.

Usually the smaller the fish the low the waste produced. Plecs have a straight intestine and food just goes through. I don't think they absorb many nutrients from their food and is why they eat so much. You can actually watch the eat and poop at the same time

Just wondering... Where do Discus fit in on the grand scale of poop manufacturers? I almost NEVER see any of my Discus pooping.

 

Goldfish are dirty little ones. My angels are clean. And swordtails are moderate.

 

Big waste producers: goldfish, larger cichlids, livebearers (for their size), catfish
Low waste producers: small, thin fish such as Neons, Harlequins, etc., Bettas

lol.. sounds just like our platys. :;jk

 

And....since they're my new obsession - puffers are very dirty too.

Aggresive, territorial, dirty, high maintenance....and yet I am obsessed. :

Yeah i've seen my plecos do it!

ok so,

Livebearers
Most Catfish =High wasters
Goldfish
Large Cichlids

While,

Tetras
Harlequins
Ottos =Low wasters
Angels
More or less any thin/smallish fish

What about the loach and the corys?
