nevermind!
well when i had them they were feisty little fellas! they usually just squabbled amongst themselves but on occasions they even chased away the rotkeil severums from their patch!
there needs are very much like bettas, soft, acidic water, just like a black water set up, low water, lots of twigs and leaves and still. they look happy enough how they are but if you wanted them to breed you'd have to change a few things, like their own tank lol
very nice all the same.
