Honestly from my experiences with feeding boiled eggs to fish is that unless the fish decide to eat it all immediately it's not worth putting it in the tank just do to how badly it will affect your water quality. Only time I ever feed boiled eggs to fish is if I have hundreds of starving fry as they will eat the entire yolk almost instantaneously. But otherwise I stear clear from adding any part of the egg to a tank as all it takes is just one day and it can start throwing your entire tank off balance.Is there any benefits to this?
Not as a staple but for extra protein?
Huh, never thought of doing that before. Definitely worth a try atleast.I used to feed it to guppies. Mixing it into gelatin helps.
