[Axolotlwoo]

Are water lettuces safe for axolotls....just upgraded my axolotl tank and would love some. Thanks for your help

In other experiences I have read about, it should be fine. however, I have never used this plant with any animals in my tanks, but I do not see any reason that it should not be safe.
