hey guys i have an opportunity to buy either some indo or silver datnoids i have always wanted them and now i can my question is if everything will be okay in my tank and which species would be better in my situation i like the indos better personally but anyways they are about 2 inches long or so and i have a flag tail that is about 5 inches a sun catfish 5 inches another dun catfish about 3 inches two pangasisus catfish in my qt tank that will hopefully soon be moved to the big tank ones about 7 inches and the other is like 4 and finally a 7 or 8 inch arowana i heard that datnoids can be aggresive i do not want anything that will be aggresive towards my arowana especially not the other ones either but do you guys think this will work? im also not sure if the aro would try and eat them i had peacock bass in the tank that were only like 3 inches but maybe i should put them in the 40 qt tank? let me know what you guys think or if i should not even get them also any advice for keeping dats is greatly appreciated thanks guys! if you have any questions feel free to ask
