Yep, of course! I was going to ask about that stuff in a second. For plants, I know live plants are better, right? On the youtube channel Fish For Thought he mentioned something about having natural substrate? Is it harmful to have the colored gravel at all?Well, figure $15 for tank, $15 for heater, $30 for filter, $20 for lid, $15 for light. It could be worth it, easy to get it all together. You will still want to get a substrate and plants and hides. The bio wheel filters are okay.
