al;right, im putting in some Apostograma Agasizi's in my 20 gallon, what would be some intresting tank mates, that wont bug them when they mate? i really like cats, but i know that'll be an issue, and how would a rubber nose pleco fare in the tank?? i definetly do not like livebeares, and would prefer to stay away from tetras (althoigh im not totally against them). im kinda looking for mid, to top dwelling fish, unless there are some very inactive bottom dwelers that would interfere with the spawning of the apistos.
