^Was thinking the same thing.
Emerald Green Cories are most often Brochis splendens (had to think twice before using the usual convention of abbreviating the generic epithet when it had already been mentioned in the thread...B. splendens is too often associated with something else!) which have been misidentified as cories.
I am a little concerned about the gouramies, but I'm also concerned about the solo kuhli and the pair of tetras...they might be happier with conspecific company as well.
