How to feed a fish in the isolation tank?

Question
Hi, I have a possibly pregnant fish I put in the isolation tank - when I put some fish flakes in, they slowly float to the bottom part (where the fish babies would go, so the pregnant fish cannot get in there). Is there a special way to feed a fish in this tank?

Answer
First of all, sorry for taking so long to answer this. My account password was lost, and it took the allexperts staff over a week to get back to me. Sorry. Now, on to your questions!

There are many foods that float. Freezen dried brine shrimp float, as do floating pellets and large pieces of flakes.
