Thanks for the replies! We are all fortunate to have such a great forum for help!
@Goldibug My pygmies are kind of bronze coloured and so very very tiny! I know the juliis (false or otherwise!) would be much larger but I was hopeful that all types of corys would be peaceful with each other. The last thing I want to do is have something else to boss them around - Anthony already does that plenty! lol
@Olympia I don't know what else would be compatible in temperament and size with a betta and 3 small little fishies ....... perhaps best to hold out for more pygmies. My fish guy says they are really expensive for him to bring in, for some reason! Maybe I'll have to special order some.
