How do i get my flounder to eat

[Luna112]

My question is very simple? How do I get my flounder to eat. I have black sand no gravel. He isn't in a brackish set up. R/O water and a ph of 7.0. I put blackworms in the tank and the worms dug under the sand where the flounder was. And I don't know if he is eating them.

I think flounders do better in brackish, so that might help you get him to eat. Spot feeding with a turkey baster or something might help. Do you have it in pure R/O water? No fish can survive in pure RO for long, it lacks essential minerals needed for osmoregulation and growth.

He is in an established tank. I'll try the turkey baster method. Hopefully it will work. Thank you
