About the 6 months rule for anemones.

I waited 3 months after cycling to add a beautiful rose bubble, currently split into 8 monsters. Barely a year later. Guess I broke the rules and got lucky lol

I had an anenome fine one day (after 12 months plus of being happy) then next morning when checking on the tank he decided to go walkabout and got sucked into the intake of my exterior filter that was about 10 years ago and I haven't kept a anenome since because not only did he pollute the tank as he went through the filter system in parts per million but I had to replace the external filter and major water changes too lesson learnt for me but good luck hopefully your anenome will stay put

some say splitting is a sign of bad water parameters

Joking aside corals/nems don’t need a cycled tank like fish, so can go in from day one, it’s not the length of time that so much matters but the water conditions, stability and light.

Every rule has an exception.
