So I'm new to the forum and the hobby itself,
I've been cycling my 65 gallon tank for a couple weeks and used the bio support stuff from my LFS
. I finally got my fish today but the clerk advised me to get 3 Tiger barbs and go back next week for more. I got the small ones and regret it now am willing to grow them out. Do you guys think it would be okay to add bigger Tiger barbs to the tank or will it cause mayhem?
