i have a question . i currently have setup a 40 gal breeder ` of the way to the top fill with water. in my tank i have 2 fire newts, 2 fire bellied toads, a mating pair of gold killifish and a algae eater( i have snails but they dont count lol). my question is since the tank is so very large and there seems to be LOTS of space underwater, does anybody have any reccomendations for any new additions i could add to my tank? im pretty much done with cage furniture except for another rock type thingy in my other corner( have one and the critters like it because they can hide).
any suggestions are welcome plz
