Ok, on the basis that the Corys and the Cardinals need to be added later...
How many Pearl Gourami can I have in this tank?
What is the maximum sized pleco that I could house and it be happy? I don't want to go any buy something like a Common only to have to sell it on later in it's life.
Can anyone suggest anything else that would be happy with Pearls/Cardinals/Corys/Plecs?
With a tank that size you should be able to have two males with two or three females each! I'd probably start with six, two males & four females and keep a close eye on the males to make sure one isn't constantly chasing the other. Obviously try to make sure the males are similarly sized, same with the females.
