Great minds & all that, Ian, lol. Roselines are kind of pricy & a bit nervous at times, keep a lid on your tank. We only had 1 jump out once when we had a new "fish sitter". I think it was just startled by a new person too up close. She just picked it up & put it back, it was fine.
I'm not sure what other fish might be ok with yoyos. Nothing small, but those 2 species would just about be enough IMO.
Maybe a single blue gourami. They can be almost semi-aggressive, I almost never recommend them. I
vastly prefer pearl gouramis, but I'm not sure about 1 with yoyos. My judgement is clouded by skunk loaches, much more than just semi-aggressive to 4-6 inch CA cichlids back in the day. I know yoyos aren't they same...& neither are gouramis. Just a thought...Research if either sound interesting to you.
Will you have plants? Java ferns & anubias are very easy & are attached to wood or rocks. Have at least 2 or 3 loach hiding areas. I've never had loaches bother those... & they might help with roselines & gourami possible nervousness when the loaches cruise up & down the tank sides. That's why you want several loaches, there's nothing like a group of happy dancing loaches
(sigh, I miss my botias!).
