I purchased some shiners from a bait store recently. I was wondering if there was more than one kind of shiner or if they were all called golden shiners. I was also wondering how to successfully breed them in my 55 gal aquarium over the winter or if it was even possible? The main concern was how many should I put in and what water temp do they need? Also what type of structure do they like to lay eggs on or in? Thanks, John
