saber tooth tetras are a whole other fish.
payaras i call em.
bick toothed tetras,or exodons,are mean bastards.
theyll nip fins and attack silver fish.
they can be kept with fish that dont have long fins and not silver.
plus they have to be tough.
these guys should be kept in a school of at least 10.
theyll easily pick each other off one by one.
the more the better.
