Hi - rlederer
I agree with you. The last thing I would want is to keep a fish alone when it does not suit. But I'd anticipate that some fish are naturally territorial, which might mean they are happier without more of their kind. You mention Bettas as an exception. Ideas of this nature are what I'm after.
You'll also appreciate that I also asked about small groups (2s or 3s). That might offer options for something different.
Otherwise, all the stock in considering would be in larger groups (certainly no more and than recommended as best practice).
As a newbie I'm keen to do my research and benefit from the experience of the forum.
Thanks for taking the trouble to reply.
Thanks also to the others who have made suggestions. I'll certainly look them up.
