Yes its cycled.TexasGuppy said:I don't think corys do well in gravel.. they really need sand. BDBS from tractor supply is dirt cheap and looks nice. My corys do well with it and it's easy to clean.
However, 500g tank? Maybe easier to get different fish.
You could do at least 20 or more, they like to be in shoals. (Same type, don't mix cory types)
Is your tank cycled?
I know this doesn't help but where the heck do you put a 500 gallon tank?!?!david00061 said:I'm using pea gravel is this going to work with cory catfish? View attachment 437409 View attachment 437410 View attachment 437411
Another question. How many of these guys should I add. It's a 500 gallon tank. 109 x 40 x 27

From what I understand, sand is best. Rounded gravel next, followed by gravel without sharp edges.Joey Fish said:I'm interested in having some Corys in my tank, so you need Sand 100% to have cories or will substrate be fine?
Yeah, I think the OP should definitely get sand as he said he's completely fine with changing the substrate might as well give them the best environment.Duardo said:for Corys I suggest sand because over time they hurt their barbels, and I know from experience. And since I heard you were looking for schooling fish I would suggest Serpae Tetras, they are so beautiful, but semi aggressive so be careful.
