So I got this tank from petco not thinking of weather or not it would hold water for my male soft shell. I know they aren't supposed to be filled to the bring from some just alittle bit of research but could this tank hold 6-7 inches of water for a turtle? I mean their made for reptiles so I figured aquatic or semi aquatic species like turtles were included in the make. Any thoughts? It's time this guy upgrades from his 20L to a 40 breeder!
