I purchased a 150 g oceanic today. I have two Festae males (1")to put in it, once its cycles. Many questions: what filtration does everyone think? What substrate? Do I need dither fish? Should I get a female for breeding? Is this tank to small for two males? Bottom feeders/algae eaters? As you can see I have alot of questions.... thanks for you response. More questions on fishless cycling to follow.
