Hello.

I just read that Yellow-perch have kind of taste buds on their lips, allowing them to choose their food.

Yellow-perch can taste food and refuse it if it does not like it.

I guess all fish should be the same.

I tried again but they still refuse fly larvae made with leftover fish.

I understand it a little, it must not taste very good.

So I made 3 buckets with different recipes.
1 Chicken manure.
2 Oatmeal with milk.
3 Oatmeal apple juice and apple rings.
