Which gravel do you think would look nicer with ADF's? I am planting the tank and I have artificial driftwood but I don't know what color gravel would look better with them and there are not many pictures of ADF's on black gravel to compare
40 gallon - Misc fish
15 gallon - Axolotl
5 gallon - Betta and ADF
20 long - Hatchling turtles and corydoras.
Black if you really want your frogs to pop, natural if you want it to look more like their natural environment. I used to have mine on bright red gravel before I knew better so I don't think the frogs care one way or the other.
