I cant afford to buy 1 unless its local, so I was hoping some people could help give me some ideas on how to make one? A little birdy told me that the caves entrance should be exactly the width of the males head and it should be 4x the length of his body. 4x SL or TL? Any chance I can cut that length in half, its gonna be a little hard to make a 20" long breeding cave in a 48" planted tank? I need it to be hidden, unless theirs a way to make it showy. No ugly plastic cans unless I can hide it in the tank. And please dont refer me to that website where the guy makes them custom through fired clay... I already know about it, just to expensive. I just know that somebody is going to link me that website...
