My green carpet reacts much faster to food than that one. I don't deliberately feed it anymore, it gets enough food fed to it by the clowns and it catches lots of food randomly at feeding time. It is probably 18"+ and hosts my Maroon clown pair.

I've had mine for...gee...maybe 15 years now? My only advice is not to feed it anything too large. I once had mine get really ill. I saved it by reaching into the gut with tweezers and pulling out a large, rotting mass of food. Basically, the food has to be digested before it rots. If it is too large, the 'nem can't digest it fast enough.

Mine has killed a few hermit crabs, snails and one starfish. (I didn't personally witness the starfish...) Mine has never killed a fish, although I'm pretty sure it cleaned up its share of bodies.

Here's a recent photo with the 'nem visible.
