Is it safe to add additional zebra loaches to an existing group ?

[Linda1234]

I know with some loaches such as yoyo it can be risky adding new members to an existing group and others like clown loaches will readily accept addition regardless of size. However I cannot find much on zebra loaches. I sort of presume it is safe to add more since they seem far more passive than other loaches but I don't know if factually this is the case. Hence the question.

I think your good, I haven't heard of yoyos being aggressive to new groups before but I’ve introduced a new group of smaller yoyos with my adults and they haven’t had a problem, i think they’re close to zebra loaches. I’ll also be adding 6 black khuli loaches once they’ve grown a bit

I agree. No problem introducing new Zebra Loaches to an established group. I think I have at least nine YoYo Loaches in my 120 gal. Never a problem adding new YoYos to the group.
I think conspecific aggression issues between Botia Loaches has to to with the space allowed & size of the hardscape.
