will dwarf snakeheads live with malawis, ive got the usual ones , yellow labs, couple of peacocks and some that were given to me that im not sure of, also there are black neons, penguin tetras, black widows, serpae tetras and quite a few others, these non malawis were in my sons tank and he had to give up the tank they were in so we put them in mine and they have been fine for over a year now, my original question is rather urgent as these fish, they are about 3 inches long may be arriving in the next week or so. any advice very welcome, thanks, kev
