I would expect you to be able to add a few Corydoras aeneus back into your tank with no trouble. Another species of Corydoras would not have the benefit of making the existing one more socially active. Cories are very sociable fish but only with their own species.
That's true. Do you think adding 4 bronze corydoras, making a school of 5, would be OK?
I would say he would be a very happy little cory considering he has no friends at the moment!
As for pairing your keyhole, you would be adding a fish of the same species and variety to a tank that yours feels is his. So he probably won't think much to that. Also, as far as i know they're very hard to sex, so you could risk the chance of getting the same sex meaning they may not get on together. Also, if they do pair and do breed then depending on the temperament of the fish in question they may be aggressive towards your others and the neons might bare the brunt of it.
I would leave the keyhole as the boss centrepiece fish of the tank and the others as the more active showy members of the team along with the corys as the clean up crew.
Just my opinion, hope it helps somehow.
) but, since I have to split the media in the current filter so that the filter on the QT tank will be cycled, should I wait a bit before upgrading the filter on the 20g so the bacteria have a chance to grow back, or should I just go ahead and upgrade to the new filter as soon as I get it and put what's left of the old media in it?
