How would a dirted tank with black eco complete as a cap and a congo puffer work out?.... will I end up with a mess of a subrate?
Fine…mine never dig in the substrate. Only rest on top of it
Tetraodon Schoutedeni tend to be called "Spotted congo puffer", while Tetraodon miurus are usually just called "Congo puffers" in the trade...
But anyway, the T. Miurus will sometimes burrow in the substrate (just depends on the puffer), so just need to be aware of that and plan accordingly, also make sure whatever you use to cap the top off isn't too sharp, although i don't think Eco complete should have any problems in that area...
BTW, what sort of soil / dirt layer are you planning on using? coz if its aquarium soil you maybe able to get away without the need to cap it unless you are doing it for aesthetic purposes?
