Thinking Of Adding 6 Rasbora Heteromorpha

[Fishmanic]

I have 3 white skirt tetra, 1 sae, 1 dwarf gourami and a nanus cory in my 35 gallon tall hex tank.  Thinking of getting 6 rasbora to add to the tank.   Does this mix sound ok to you?

Seems ok but you should also up the white skirt tetras and corys to six of them. They are schooling fish and need at least 6.

I was thinking of getting one more skirt tetra as well as 6 rasbora.  But can't find nanus cories anywhere local so he will stay as the lone cory in the tank. I could move him into my 30 gallon if need be where there are 3 Julii cory and one skunk cory.   He seems quite healthy and content in his present home and is  very active.

I agree on upping the other fishes numbers before adding another schooling fish, but it's your tank

Definitely move the lone cory.  This is a highly social fish that lives in groups of hundreds, and all the cory sources will recommend no fewer than five in an aquarium.  It doesn't need to be five of the same species, though tat would be nice, but just having them together makes a big difference to their health as they will be more settled.  And you will get more enjoyment not only from healthier fish, but their antics and inter-actions.  For 20+ years I have kept large groups (30-50 depending) of corys in my largest tank, and there are several species represented.  Some remain together within their species most of the time, while some don't seem to care; my C. duplicareus and C. sterbai are especially prone to chumming around together in groups of two, three or more.
 
The White Skirt can be nippy (nip the fins of each other and other species) so having more of them is wise for this reason as well as just the fact that being a shoaling fish more is always better.
 
If you add the rasbora, a larger group is better for these.  Trigonostigma heteromorpha (the Harlequin rasbora) along with the two closely-related species in the same genus are best in groups of 8 or more.  This species is actually a much better match for the gourami, so another option would be to remove the three white skirt tetra and add the rasbora.
