Just got an ADF from the pet store to put in my 1 Gallon tank... I have green medium sized river rocks and 2 live plants that have sprouted and a small clay pot in there for him to hide in. I don't have a filter or a heater because petsmart employee said they can live in 70-78 degree water and they breath air so no filter needed. I am going to do water changes of course like with my other two bowls. Any suggestion/advice anyone could give me would be great :)
