Technically you are at your limit but...... assuming you have damn good filtration on the tank you could probably get another gouramie in there. Maybe two. Rules can be bent a little IF the tanks are kept in tip top condition ALL the time. Hence why I run two filters in my bigger tanks. All those fry etc make alot of mess.
