will my fish eat/injure a new smaller fish?
First of all, many thanks to everyone who helped me out when my fish was injured several weeks ago. He is doing MUCH better now and is almost fully healed thanks to your wonderful advice!
I am getting ready to move him to a bigger 55 gal. tank, and once that is done I plan to start shopping for some new fish to keep him company.
He is a large (6 or 7 inch) wild goldfish who will certainly get much bigger quite quickly once I put him in a larger tank. I'm concerned that the only place I will be able to find the same kind of fish to keep him company locally will be in the feeder fish tank at the pet store, so they will be SMALL.
Will this pose a danger to the new smaller fish? Might my big fish consider them a snack instead of friends? Territory issues? Do I need to make a special effort to find fish of a similar size? Is there another kind of fish that would make an equally good or better companion?
Just want to be sure I do this right (and yes, I'm planning to keep the new fish in a separate tank for a while before introducing them)...
thanks in advance, everyone!
