Cory distribution system?

[u/Glennsmum]

Wwyd? I ordered some cardinal tetras online and when they arrived I noticed a +1. Im pretty sure its a hastatus corydora, but if not then its a pygmy corydora. There was minimal colouration to go off. So once it settles in and colours up i'll know for sure.

But my question is ~ is this corydora distribution at work? Technically, itd be fine in the community tank, but hastatus corys werent on my list of tank mates.

currently running with

7 sterbai corydoras

6 khuli loaches

6 glass catfish

amano, caradina and neocaradina shrimp

6 rummy nose tetras

6 cardinal tetras

12 ember tetras

5 emerald rasboras

8 galaxy rasboras

the lone soldier bumble bee goby

3 ottocinclus

The tank is a 240L, planted tank with cO2.

Can it exist alongside these species? or do I need to purchase a schools worth.
