I know this topic is old but I can not find out how long C. julii live ? I have had two in my tank for about 4 years now. Since they are not very big fish I don't believe there life span will be too long. I am just wondering if one day pretty soon I will find a floater ???

always heard that sand is better than gravel for cories but just wanted to make sure.. would cories do just as well without substrate? what does substrate do to them?

Hello joshua

I use small gravel in all my tanks and the corys do fine with it. Many people do like sand for their corys, though, and I plan to try some in the future. The important thing to remember, whatever you use, is that it be small and have rounded -- not sharp -- edges. This is because the barbels of the corys are delicate and can be easily damaged by rooting around in such substrate.

In general, people use gravel or sand bottoms because it provides additional areas in the aquarium where the beneficial bacteria can grow and thrive. It also serves as a medium to grow rooted plants which benefit the tank, provide shade and hiding places for the corys, and of course, look great.
