In my 500 i have a fair size group - maybe 30 or 40 not sure of the exact number. One thing i've noticed is their behavior during the day they stay in the open on the left side which has almost no plants but when the lights go off they move to the left side which is heavily planted and settle down in the plants. This behavior is not unique to them as i have several other fishes in that aquarium that do the same thing.
As for the large(r) fishes in the aquarium - are a group of near if not full adult mix of geo albios/dicrozoster. These are not small fishes and in general i do not recommend them even for a larger aquarium like 600 or 500; they really need something like 5000 gallon aquarium (not height but simply more floor space).
