Which dithers are most hardy

[UTEP]

Ive been using giant danios in my sa/ca tank.... jag ,black belt, JD, RD, uro, bleekeri ,3 convicts , GT, firemouth, Flower horn, texas, and a rainbow, i got 10 danios from petsmart about 5 months ago so far i've lost only one....i tried using silver dollars and barbs they got crushed within a week

Cause most add dithers last. Had you had the SDs first they would have been fine-Tinfoil IMO get too large.
