How many to add

[skiweeangel]

Am restocking a 55gal. Right now I only have 4 giant danios in it. Water parameters are 0,0, <5 pH 7ish. I want to add a school of tigers. Do you think adding 2 more danios and 3 tigers is too much at once? Or should I add three more danios and then the tigers?

Add the danios, wait a bit, then add the barbs. Tiger barbs like to be in large schools 10+ to limit aggression.

Ok that's what I was thinking be always need a second opinion.
