How are Farlowella with discus

I saw some discus tanks that had Farlowella in them, how safe are they to keep with discus?
Anyone breeding them in US?

I had them in with my discus a few years back.Mine did go for the slim coat and had to be removed.They left scratch marks on the discus.I had 4 in the tank and all of them did this.This is my experience but I've seen videos on youtube with discus.

Thanks Mervin, yes I see them more now

When considering compatible tank-mates for discus, it's appropriate to keep in mind than ANY catfish species (whether or not they originate in the Amazon and can handle the higher discus temps) could display the potential inclination to take a liking to discus' slime coats as part of their diet, particularly as the grow older and get lazier.
