awesome thanks for the info!It’s a hard one to answer, if you aren’t qting well 77days between to ensure it’s safe but other side is if not qting then your rolling the dice anyway so does it matter? It’s weird me writing this but I added a royal gramma to my tank from LFS and it wiped out my entire tank and then I had to wait 77 days before cud add fish, that was heartbreaking. But u can buy qt or captive breed fish you can also do a the quick qt safety stop or something it’s basically back to back baths meth blue and formalin. But wud just hate for u to add a fish and next week add another and the first one shows signs. If don’t have holding tank. But u want to be adding weekly well I’d split it with some cuc. Least 2 weeks would be more likely to show signs. I wud just make sure before u add anything to tank that they and u r happy before adding again. Tank will do a mini cycle with every addition.
So if fish happy eating and good form. Tanks good shape nutrients maintaining that’s ur next addition. May that be 2 weeks or 4 weeks etc. That’s my TLDR summary lol.
