Is Flourite too sharp for Corydoras?

[WeehawkenFish]

Hey guys, I have 10 cardinals and 1 apisto in my 29-gallon.  I notice that a good 75% of the food I feed (when feeding nano pellets and bug bites) just ends up going straight into the substrate.  I was thinking of adding some corydoras to the tank, do you think Flourite substrate is too sharp for them?  Also, are corys the right choice here?  Not sure I can get shrimp with an apisto.   Thanks.

I think corydoras would go great in that tank! I'm not sure how much of an algae eater they are but if your looking for algae eaters here is a list:

-Ottocinlous 

-Hillstream Loach

-Bristlenose Pleco

-Amano Shrimp

All of these fish/ invertibrates will do fine with your tank mates. (the amano shrimp is bigger then other kinds of fish, so it shouldn't be eatin)

Thanks @James Black.  I have algae growing a bit on the substrate as you can see, but I have it in check everywhere else in the tank, as well as lots of snails.  I'm more concerned with how much food ends up uneaten in the substrate.  Can't that lead to ammonia?  I tried ottos once, they wouldn't eat anything and all died within a month.
