I stopped doing live feeders a few mos ago, and my aro never even bothered the guppies, (before I knew they weren't so great to feed), so he lives peacefully with everything else edible size. That's why I was suprised. Now he's happy, and my guppy girls have a boy. Just no loaches. I bought the biggest one they had, I guess I'll wait for a bigger one, I like Clown Loaches.
