I guess I should try out the wafers, quite expensive though. Floating pellets is also difficult for the turtles to eat, because they have to keep paddling to stay afloat. Furthermore, the turtles just lack accuracy/skills required to efficiently gulp the floating pellets.

On the contrary, one good thing out of this is that I know when they are hungry. My turtles will paddle up nearest to me when they are hungry.

Also, I have to separate my 2 turtles with dividers now that they have grown larger and more aggressive. The bigger one will attack the smaller one
