Hi Charlie!! Also, Welcome

There are some incredibly knowledgeable people who just happen to love fish.
Although I'm still considered a 'newbie', I watched this forum for a long time before joining, while making every mistake in the book when I decided 'it would be nice to have some fish to care for and look at', adding two years ago.
I now have around 300 fish, and 5 aquariums - most of which are the result of happy, healthy Panda & Peppered corydoras. The majority of my learning has come from the wonderful people in this forum.
The other fish I adore and have happen to be kuhli loaches - 3 striped and 2 black.
I am on the process of trying to rehome my 6 hectic magnificent, constantly spawning Peppered Corydoras.
Since having them, although they are great community fish and literally prefer to bed down next to their close buddies- the kuhlis - and the kuhlis are just as happy to have them close, the kuhlis don't come out to noodle around in the main tank like they used to when I only had my pandas.
I'm pretty sure it's because of the size, speed and bombastically unpredictable torpedoes chasing each other around whenever they aren't resting. The peppers corys are also voracious and pushy eaters.
I would like to get some more loaches as well, and I just can't keep up with the sheer volume of eggs the peppered corys produce.
Therefore, I don't recommend Peppered corydoras.
I 100% encourage you to consider Panda corys though. They are much more suited to the easily startled nature of kuhlis. The gentle, friendly nature of the pandas meant there was no competing or rushing when it came to eating, and the kuhlis were comfortable being out and about with the pandas most of the time - including daytime as I've learned that the fish seem happier with 3 smaller meals than 1 or 2 larger ones. I think it appeals more to their grazing nature, and the tank stays cleaner because of it.
I also have cherry shrimp and a single super calm mystery snail
Originally, I had a small school of green tetras who got along with everybody, but sadly lost them to ich when I added rasboras without QT way back in the beginning. I learned that lesson the hard way!
I hope I've been able to give you something constructive to think about and wish you all the very best with your kuhli tank!
I'll leave you with a couple of photos of my kuhlis - being kuhlis!!
