Fish Crazy
a minimum tank size for a silver arow to live comfortably is preferably a 6x3x3 but longer is better, as they are fairly flexiable unlike other fish such as a pangasius cat or red tail catfish so their tank does not have to be as wide as they are. Silver arows are usually peacfull, ive had 3 all live in harmony with fish easiy enough for them to eat. Jardinis have a bad reputation to go agro after the reach 8", but there are occasion like CFC where they will live with other tank mates.
Hope this helps
