Today was a sad day for me. I got a silver aro two days ago. He was about 6". I put him in my tank with an oscar, lima shovelnose cat, blood parrot and a clown loach. I was a little worried he was too scrawny as my oscar is 8" and the cat is about 10". He seemed to be doing ok and was eating good. Today, when i got home i looked at the top of the water and didn't see him. I thought maybe he was behing some tall plants i have towards the back of the tank. I turned on the lights and i noticed the shovelnose's stomach was bloated and no aro! This is the second fish he has ate. I really want an aro. Did I buy too small?
