Its forever been the arguement in our house. The OH would prefer big fish and I'm having to constantly explain that Oscars need a much bigger tank...I was a bit worried about the size of CPD's honestly. Have not had fish quite that small, but I would have the space if I stuck to only 2 shoals. The kids would probably enjoy something a bit bigger though.
I actually prefer the look of a large shoal of small fish.
I was looking into blue panchax recently, temp range seems to fit the cherry barbs and hardness is quite wide ranging..
