The fish typically catch on.
I bought a wrasse at a pet store and it ate
When I brought it home I put him in and feed the tank a little later.
The fish saw everyone eat but didn't chase the food.
After about 3 days as soon as I took my hand to the top of the tank he was right there with the rest of them waiting to eat...
Just say...
But I can understand the need to want her to eat fast, I know there a pretty expensive fish...
