what tank size should I purchase for four at the most and is four an 'ok group' for Dendrobates Leucomelas? How should I deal with ventilation for plants, if i use a glass top? I was hoping to do a cool background like some I've seen on here...but where to start haha!! And as for the false bottom....Does it need a 'drainage hole'? Lastly, I have a large magnolia tree in my front yard...I have heard darts like the magnolia leaves. How can I make sure they're clean? A good rinse?Thanks guys!! You are the best!!
