Another Tankmate Suggestion Request.

Hi - hubby has just started fishless cycling his new 60 cm / 57 litre tank....

I know it's at least a month down the line, but has anyone got any good suggestions of what other fish to add with these below... he (we) just can't decide and would love some ideas from experienced fish keepers:

He's decided so far on  6 harlequin rasboras and 4 panda corydoras .... we both love the idea of these.

What would be good with them? A difficult choice due to  tank size (standard internal filter)

thanks 

neons i would leave till the tank is about six months old
other wise they wont survive
