As a fish and bird keeper/ breeder I often end up with a similar situation. I sell what I can privately (sometimes racked with guilt if I think the creature wont have as fullfilled live with the new owner as it did in my care), I often sell to a pet shop that I trust (usually as a last resort) or I end up keeping the extras until thier dying day. None of these options really sit well with me on an ethical view, with regards to over crowding but as a pet keeper you have to try and make decisions that suit your circumstances and ability. Too often I see give away to good home X numbers of Dogs and Cats, both of my dogs and 1 previous dog where unwanted and only in extreme circumstances would I EVER consider rehoming my cat or dogs ( I might point out that as a kid we moved house interstate a few times and our pets came with us so moving has never been an excuse for me to give away pets). So I would suggest to you is if she really doesn't want the guppies and gourami any more than find a means to correctly (in other words not dump in a local pond/ creek) rehome the fish and then research all the needs and chances of the new fish creating the same problem. By for example keeping tetras that are less likely to breed in huge numbers in a standard community set up, while other live barers or fish that relentless guard their fry can/ could recreate the same issue of being overrun by babies or getting "bored" with the setup and it's inhabitants. That or keep a male only tank but it too has its problems. In Australia we are getting stricter and tougher laws on what can be kept simply becuase so many species of previously loved but now unwanted pets have simply been let go into the environment, it is wrong and against the law but still today I hear of people still carrying out this practice.
Ultimately it is her conscience that she must be able to live with regarding all her decisions, we can only guide and advise by what our consciences tell us.
