Hey guys! To explain my life:I have two, three gallon nano aquariums. I'm 16 and obviously still live with my parents, who won't let me get anything else bigger.The exclusion to the above statement is that my dad MAY let me get an aquarium, because he keeps on saying how much he loves terrariums that have water and land.I would like to offer to him to do a father and son project on making such aquariumGreat, so now that we're on the same page, this is a huge deal to me. My question to you all is what stocking could I do? I was thinking some form of crab. Could I keep some form of fish with it? Also, what plants would you suggest for the dry side? I'm pretty well versed in aquatic plants, but not so much in terrarium plants.What should I use as a retaining wall to hold back the soil from the body of waterShould I do just soil all the way down, or should I use some sort of filler?
