I'm trying to make new diets for my fish, but everything I come up with has too much protein. Is there anything for fish that does not have much protein? Or that doesn't have any protein at all?

May I ask why you are wanting a diet with no protein at all?
I can understand limited protein, but I am affraid that if you do no protein at all your fish will not get proper nutrition.

Ill agree with Laurie, you do need protien.
Peas are good any greens are also very good for your goldies.

Agreed, they do need protein. Especially if you have fish with wens, the wen won't grow without enough protein. Also very important for breeding.

Why must the Government cut from vital fish protein...oh wait you can food with extra protien but it's expensive peas will do fine

If you check the back labels of goldfish food, protein has the most percentage in them. It helps goldfish grow big and quick!

Protein is good for your fish. Of course, too much is bad just like not enough is. If you want to feed something high protein, feed some veggies with it (veggies have low protein) to make it more balanced.

In fact im using high protein base gel, with soy, peas, spinach and yams on those days i dont feed meat and it also contains HIGH protein and LOW carbohydrate percentage - the Goldie atkin diet!

as i see it SOME vegies may not be all that great as like i mentioned before it's ideal to have a higher protein percentage then carbs(which vegies contain in starch form) as it is there natural diet most of the time, and the only bad thing about a high protein diet is that it may lead to high nitrate levels through cycling which is poison at high levels. this problem can be solved by having a plant since they use it up for growth.
