My RD is 5? (edit, maybe more like 4? Bought at 3 inches, so IDK), welcome to the forum!
My RD lives with 3 giant danios and 2 rosy-red minnows I dewormed and quarantined out of the feeder tank, lol. She ate one rosy red experimentally (there were 3) but must not like the flavor...
She also did great with her buddy chinese algae eater, but the CAE died in a filter upgrade accident. Stepped away to build an intake cover right after I got it running and the little torpedo shot right into the filter, I couldn't save him.
Oh, and she lives in a plastic "pvc" noodle, ha ha.
I wouldn't put anything with her that I don't expect to see murdered one morning, even though she's been relatively mild for a RD so far.
