Yesterday I got 5 itty bitty ember tetra fry for free from petco. I put them in my fry tank with guppy fry the same size as them but the guppies seem to be picking on them. I don't have any more tanks to separate them into. Suggestions?
I would not keep these two species together. As for what to do, since you cannot separate them there really is only one option, return the ember tetras, or the guppies.
