So my questions is how long do you leave them in your tank? I just got a filefish and he along with a tang will pick and eat from the clip whenever they want to eat. It's been in the tank for 2 days now and even though it looks fresh i cannot help but feel like i need to pull it. I currently have a piece of lettuce on it. Perhaps i put to much? I'm sure i did but even with a smaller piece, how long should i leave it in? Thanks for any advice.
