Title says it all, I'm looking for ideas to stock my 20L, current inhabitants are just a Blue Gourami and an oto, the oto can be moved out into my main tank but the Gourami should stay as its in there because it liked to pick on my other Gourami.
What I'm looking for;
Only 1 type of fish
Species that will do well in a pH of about 8
A species that will do well in a high traffic area - Tank is between kitchen and living room
An active species
I'd like to dabble around with breeding this fish species
What I'm not looking for;
Livebearers - I have enough in my main tank
Fish that you have to separate - Like my Gourami, because I only have so many tanks
Fish that don't do well with live plants
It is a possibility some day I may be able to move the Gourami back to the main tank but not right away, so I'd like to try my best to keep it compatible. All comments, suggestions and criticisms are welcome.
