No special requirements for brochis,these don't seem too fussy over tank temp either, just keep/feed as you would corydoras. They are super little cats quite often overlooked but look great in the right light.
awesome stuff.. I have a fair few of them in my planted tank. they look great and are very active. great colours too once they get a little larger, you can see the armour plates on them and that looks really nice.
I would personally not keep them in a bb tank cause they do enjoy sifting through the substrate.
