Veija cichlids are very aggressive just like some of your more common American cichlids like Amphilophus, but I rarely see them living in solo tanks! I've kept vieja synspilum before and it was very aggressive....how do you think it would do in a tank alone? I know it takes them much longer to grow as well; but I think 1 Veija with maybe some silver dollars would look awesome in my 75 gallon tank! what do you think?
