we have a 10 gal
tank and had 5 Gold Skirt Tetras in it. Two have died in the last number of weeks so we thought we would add a couple of fish. LFS
said that Black skirt tetras were compatible with other tetras. We got two. they look the same as the gold skirt except in color.
Last night (first evening in the tank) the black skirts were chasing the gold skirts around. Kind of charging at them, not chasing perpetually around the tank but a number of short little runs.
Is this aggressive behavior that will hurt our original Gold skirts? Will it even out? Should we pull out the Black skirts and give them away or will all turn out okay in the end?
thanks for your advice
