I was watching TV then I heard some commotion in the tank. The aro was splashing water around. I thought that was strange because he usually isn't very jumpy, so I went over to take a closer look and I saw he had caught one of my smaller 3" loaches. I grabbed a net and was able to get my aro to release the loach. He swam off with only a few scratches. They didn't look that serious, but the loach died 3 days later. I love the look of tanks with monster aros with a school of loaches. Some people are able to pull it off, but it's a gamble.
