Ever thought of putting together a community of fish that share some quality? Like...

Fish with orange and black vertical stripes: clown loaches, tiger barbs, distichodus sexfasciatus, kuhli loaches, and the like (not claiming that all of these fish are compatible, just examples of the category)

Fish that make audible sounds: pygmy gouramis, raphael catfish, Senegal bichirs, grunting toadfish (bw), what else?

Fish that swim/position themselves weirdly: pencil fish, headstanders, upside down catfish, and the like.

Any other ideas for an odd community theme? Or other ideas for the lists I mentioned already?
 
another one

fish that look like plants/leaves: leaf fish, ctenopoma (kinda), african butterfly fish, banjo catfish... sure there's a lot more
