Salt and pepper cories good on bottom.

Theyre not equipped to handle the heat of a discus tank. Max temps for them are about 77-78 degrees.

Hi Guys,
What about Harlequin Rasbora. Would they make suitable tank mates?
Peaceful and big enough to not end up as dinner for a Discus.
I'm starting a new tank and was considering them.
Are they not popular for a reason?

Bugger!
I've seen them with Discus in photos and videos, but maybe its pushing the boundaries a bit too far.
Here's an example:

Had anyone considered black emperor tetras, not black neons.

no i haven't, i actually don't see then in LFS much, which is probably why. i wouldn't be afraid of trying them though, and they get bigger than black neons

WoW, Discus will eat cardnial tetras? I didn't know that. People who like to show their tanks usually have these tetras schooling in the tank with Discus. Good to know.

What happens if you introduce small discus in with Cardinals and Neons?

I had very good luck doing it this way...for a while. Everyone got along great, the discus never bothered the tetras at all. Then one day the discus spawning began and I learned two things very quickly. First, tetras love to eat wrigglers and new free swimmers and are quite the threat to them. Second, discus parents can take GREAT offense to their babies being eaten by tetras and will go to great lengths to eliminate threats to them. The only tetras that survived were the couple that hid under driftwood that I caught before the parents did.

I've tried lots of things with my discus. What I find is that discus eat up emperor tetras much more readily than cardinals, possibly because cardinals swim faster. Eventually though, they'll eat up all the cardinals. Rummy nose tetras seem to do well in my discus tanks, although I've never had large swarms of them.

I notice that discus will also eat the pygmy cories, C. hasteus and C. pygmeus. They don't last in my discus tank.
