Lovely choices I wish I could keep rummies sooo bad but my angels eat them. My angels grew up with espei rasboras which are nearly identical in shape/size and never give them a second glance but that wasn't the case with the rummynoses unfortunately. Fish are so annoying sometimes! My angels are not fully mature but are getting pretty big so I'm going to have to go with something with the body shape of your bleeding heart tetras for example. Oh well!!
