corys vs kuhli loaches?

It doesn't really matter IMO. You will need at least 6 kuhli loaches for them to be comfortable. Their bi load is a lot smaller.
Cories you will need at least 4, but 6 would be better. They get decent size and therefor their bioload is bigger. However they will also scavenge leftover food etc. They are both fun and nice addtions. I have kept both in same tank before....

I have both in my planted tank. 5 khuli's and 10 corys. The corys are more active and always out and doing their janitorial work. They hide out in the hygro forest when they rest. The khuli's stay tucked under a piece of driftwood or well hidden 80% of the time. I see them mostly at feeding time and water changes.

I say both are fine in a planted. Never the slightest bit of problem with either in the plants.

They both have interesting behavoirs. Khuli's are comical little critters. They "dance" during water changes, drape themselves over plants and it's always fun to "spot the khuli" in my tank. I love how busy my cory's are and I really enjoy watching their breeding behavoirs. I've never saved eggs yet because..well...i'm lazy. But if I'm up early enough after sunrise to watch it..it's fascinating. The other fish enjoy it because they get eggs for breakfast.

It can depend on the tank size, a bunch dwarf cories would be nicer in a smaller tank than either kuhlis or regular cories. I would keep at least 6 of any 1 species but more is always good if you have the room.

I would vote for Corydoras as Kuhli Loaches are known to be shy animals!

I also say Corydoras. What I like about them as well is that they are small. Also, kuhli loaches tend ot be nocturnal so you will most likely not see them during the day.

Same here with my khuli's

I am terribly, terribly biased, but I have to vote for kuhli loaches.

Mine are out constantly, day and night, dancing their little hearts out. They love plants and they're good for a little clean-up, but aren't an excuse to overfeed.

If you keep them in a large enough group (6+) with enough hiding spots and shaded areas, they'll be out! I've thought about setting up a webcam for my kuhlis because no one believes me!

They have great personalities and they're so fun to watch. Great little additions to planted tanks.

Both work great I have both in my planted tank and both the cories and the khulis swim around non stop

Khuli's seem too small to me in tanks larger than 20g, corys are much nicer looking and more active than khuli's too IMO
