VIEJA are 6-10" i have a shoal of colombian red fin tetras in the tank since cycling and have never been bothered by the vieja. and last week added 2 2" jd i rescued and again no problems.but then again maybe i will have enough when the 6 silver dollars come from the grow out tank to join my 2 4 yrs olds.
thanks for the advice, will have a good think about it
