I am a big fan of the platinum dragon scale male bettas. Unfortunately, I have at least two of them that are pretty much blind due to what people say is “diamond eye” or “dragon eye.” I thought it would be helpful to others to know that when I had them in a 3-5 gallon tank they had a really hard time finding their food. So much so they almost never ate. However, When I moved them to a 1 gallon tank they found it right away.
I know someone is going to say you should never put a betta in a 1 gallon tank but in this case it actually allows them to actually find their food and survive. I realize it’s not ideal, but I figure it’s better then death.
Hope this helps anybody struggling to feed a blind betta.
