I have a pair in my 60gal community tank, they are pretty easy going (bit pouncy when they have something to protect). I have Cory's (pygmy and standard size), siamese algae eaters, harlequin rasboras, Ottos and apistos. The only fish they have issues with is the apistos but that's not overly aggressive.
Lots of plants and caves and I agree with Colu about food but they aren't the fastest at getting to the food drop so you might have to keep an eye on that if you have more voracious fish with them.
Oh and I established a male then added a female which worked very well. But the other way round did not work well for me at all.
