Well kip I tried all sorts of stuff to feed my 3 yuma's, I tried a large piece not a 1/4 of a cube, more like 1/10 a cube, I used plastic tweezers and placed the cubes as close to the mouths as possible, none of them ate the food, one got it stolen by my clown, the other two kinda threw it off themselves, then I tried getting a small piece and mixing it with water and sucking it up with a salifert syringe and squirting it at the yuma's, they didn't seem to get any food off of that either, I wonder if they catch freeze dried cyclopeeze when I feed it to my fish?
