Are safety pins good food?

[shekes]

I have over 40 species in a dozen of tanks and all eat the food I just throw in the tanks..., except for one...

My 1.5' black aro eats big shrimps I hang in the tank on a "chain" of 4 safety pins. I have been doing it this way for several months now but wasn't happy with it because I was afraid that eventually she'll eat the pins. Usually I watch her rip a shrimp off this "chain" and then I replace it. But, if she doesn't bother, I sometimes walk away and then sometimes the 2.5' SAL gets it.

Wednesday after the WC, I hung the pins in the tank planning on feeding but forgot.
Later on I heard a noise and three of the pins were gone. The pins are around 1'-1'5.

Theoretically it also could've been the SAL or even the ray, but I am pretty sure it was the aro.

What can happen?
What can I do?
Should I keep feeding her?
(I immediately inspected the gravel. The pins are gone)

buy a feeding clip they make them to hang food on the inside of your tank their plastic with a suction cup i would use one of these a safety pin could cause some serious internal damage

well hopefully it will rust away in his stomach like some fish hooks do but just watch him carefully if he quits eating you have a prob i would start adding aquarium salt if you dont already salt will help to break down the metal faster by rusting it i hope he turns out fine keep us posted,,,,,,,,,,,,,,,,,,,he might pass them but i dont know for sure
