In my 29 gallon, I have 2 huge goldfish that eat just about everything, including the bloodworms and the algae pellets that are meant mostly for the julii cories I have. I've had 3 of them for at least a year though, and I recently bought another two. Is there some technique I can use to get the food somewhere the goldfish can't reach, like with a cup or something. I also have a 10 gallon with a young blue cobalt cichlid and a black skirt tetra. I could move the cories there, but it might be too small, and the cichlid might bully them. Thanks. And the by the way, I will not get rid of my goldfish.
