Whee! Those look like big happy swords. You can try to "stunt" them by removing the large outer leaves. Both the swords & crypts would like a root tab. The staurogyne doesn't look as happy. I try to get to it to be more of a ground cover but it's a bit more work than swords & crypts. I love all crypt species.
I'm sorry, I can't really see you althernaria. Could be I don't know what your specific 1 looks like I've only tried "rheineckii" or mini or whatever I was given...not successful for me very long term. I hope you have better luck
