Which Cory Cats Will Do Best?

HI guys! I'm thinking about getting a school of 5 or 6 cory catfish for my 20gallon. But I'm not sure what kind would be best in the tank. The pet store employees said all the catfish are fine in water that's 72-82 degrees but I don't fully trust them since they said I could keep 3 goldfish in the 20 gallon with bala sharks and a betta

Tank info:
Size - 20gallon
Temp - 79 degrees
Plants - 6 amazon sword
Substrate - sand
Stock:
1 betta
1 swordtail
1 kilifish

 

Corydoras Aeneas would do well. They’re labeled as “bronze corydoras”

 

Pandas are nice. I have one in my tank take. I should have bought more. I intend to, but hes pretty active in my tank, and I'm not very good at this. so I dunno I guess they know how to live lol

Panda corys need cooler water though. Bronze or emerald corys will do better in 79 degrees.

Ok thanks. Would any be ok in 78 degrees (if my fish are ok with that temp I could lower it. haha I want what's best for them ) If not I may look into the emerald or bronze, thanks!

 

I agree with the brozen cories. If you can find albino ones, they look AMAZING on a dark substrate.

 

I really like emerald green. They're really nice looking and from my experience much easier to take care of than say the pandas.

 

I feed my Cory’s shrimp pellets (2 different kinds) and I think they also get some of the new life spectrum that sinks to the bottom. Is that enough? I heard bloodworms (frozen) are good for them but I feel weird giving them worms. They look weird. Lol!
