I love how these guys look, though I have some questions about them 1. Can they be kept with fish(i have angelfish and neon tetras, though I'm not a huge fan of the tetras) 2. How big do they get? some sites say 1 inch, some say 3 inches 3. What would be a good hiding place for one? I have a Smallish(about 4 inches) ceramic "cichlid stone". would that be OK? 4. Will they eat my plants? I have java moss, java fern, Mare's tail(kind of like elodea/anacharis), and another stem plant which I forget the name of right now. 5. Can I keep more than one in a 29 Gallon/110 Liter tank with 3 *small* angelfish? Thanks in advance for the help!
