I have a small outdoor pond stocked with some koi, clown loaches, plecos and lots of guppies. I'm thinking of getting some other fish like sail-fin and balloon mollies. Would they do alright in an outdoor pond? Also, what about an archer-fish? According to a certain site I visited, although they are technically brackish water fish, they're supposed to do okay in freshwater ponds. Would anyone here be able to verify if that is indeed correct? Thanks for reading this.
