Fauna for the walstad bowl
'ello all! As you may know, recently I started a 2 gallon 'walstad' bowl (it isn't technically a walstad setup...I'm using an air powered filter). The tank is currently cycling (ammonia read .5 ppm yesterday!), but I would like some opinions on some potential fauna before that happens. I was considering a pair or small group of Elassoma or Dario...they're tiny, inactive, don't have much of a bioload...but what are some options you guys would suggest?
