Use your best judgment.
I have a breeding pair of JD's in a 55. They are in there with 2 bristlenosed plecos, 2 pictus cats, 4 giant danios, and a gaint algae eater that my gf dropped in.
They are fine. However, I do not see this being fine for life, unless I get rid of everything but the JD's when they get bigger. As of right now however, everyone is happy and healthy.
