How many corys in a 9 gallon tank?

[ApynAquarist]

I have a 9 gallon tank that I used to keep my male betta in. He died a few months ago and I emptied the tank to take to my new house. I decided I want Pygmy/panda corys. I have no idea how many corys I should get though. I don’t want to overcrowd the tank but I don’t want a too small group. Also, what tank mates would go well with Pygmy/pandas.

For a 9 I don’t recommend pandas. They will be fine when young but they get a touch to big and are to active for a 9 plus they breed like crazy. 
 

Pygmy I would do a group of 10.  I kept 10 in a 10 and as they bred it went to 20. They didn’t have an issue but at 20 they became so active I upgraded them.

Most nano schooling fish, like rasboras & smaller tetras. Endlers!

Thanks for the information I didn’t know what was overcrowding and what was not a big enough group. As for tank mates, I like the look of rasboras but have never kept them! I don’t like tetras that much though.

For anything smaller (20 Long being smallest recommended) I would do 6-8 as a start. As mentioned, they breed pretty regularly.

Something like dwarf Corydoras would be my choice though. Hasbrosus, hastatus, etc.
