I just set up a 12 gallon cube tank witha penguin filter withe the bio wheel and i added some black sand subtrate that has already has all the bacteria because it was from a hundred gallon tank i have and i wanted to make it a live planted tank with 2 Ram cichlids male and female and i was wondering if anyone has any experience with these or with planted tank and advice on it. Also is there any other fish i could put with them?
