The common ones anyway. The comets and Koi. I put some feeder fish in my goldfish tank and the goldfish went nuts. They attacked the little fellas with no mercy and even fought among themselves. They acted as though they were never fed, but i feed them every day. It was kinda scary. Did you know what was lurking in your fish tank.LOL:FIREdevil:
 
those rosy red minnows except there not red. i gave the fish a little more food and they quieted down. No survivors by tomorrow i bet.
 
I made that mistake with my goldfish once, they also went crazy and ate a couple of the rosy reds, goldfish will eat other fish if it will fit in thier mouth, they will eat minnows and nip and crayfish too.
 
I didn't quarantine them. i just hope some of the rosies survive the night.
 
The rosy's generally come complete with a nice range of diseases. Keep an eye on your tank in the next coming weeks. You may be doctoring up some sick fish soon.

BTW goldfish are omnivores. I feed my big ones ghost shrimp, duckweed, mutated guppies, lettuce, peas, elodea, and most of my plant trimmings from the other tanks. This is all on top of the staple of pellets and algae disks. I had some rosy reds in the tank at one time that the goldfish ate all of the fry and eggs from as well. They also devour small pond snails quite rapidly. The only place the pond snails survive is my canister filters. I tried to get some malaysian trumpet snails populated in the tank as well--No luck. Last water change my big female shub tried to take a bite out of my finger too.
 
I had an open top on a goldfish tank once...mostly just big comets. The cat decided to take a drink out of the top of the tank and got nipped in the tongue, he never tried that again!

:iagree: Always quarantine every fish you get before introducing to the tank. Feeders are no exception to that rule at all. We learn the hard way otherwise.:duh:
 
Well not a single feeder is left. The fish apear fine but its probably to soon to tell. I hope the goldfish dont get sick.
