I run a 2213 on my 54 litre fighter tank. I use the spray bar and turn it to face the glass. Its not too much of a problem for my fighters and if you plant the tank out the disturbance will reduce further. Good tank mates are neons, cardinals, platties, bn. Angels, barbs, male guppies are not recommended but the ones I definitely would not put in the tank with them are the barbs. Leave a space for the male fighter to swim in when planting, mine like to be able to swim from end to end.
