If you do want a trigger look into blue jaws. The only issue w your tangs could be the purple. Absolutely a beautiful fish, but one of the most aggressive. I have in the past seen them chasing a naso. Naso tangs tho very passive except with other naso tangs.
Imforbis covered the rest
The dead is what starts the cycle. Death equals ammonia, which starts the bacteria that consumes it. Adding cured live rock is already full of said bacteria so it then spreads to your dry/dead rock. Eventually turning it live aswell
W no fish in your tank, just rinse the rock and put it in. Add a small peice of live rock to help seed it and your all set. All you need is normal sw tank specs. Salinity, temp, ect
Hmm, now my maroon is in a 29, its going in the 75 but has been in my 29 for about a yr now. Doesn't bother tank mates, but adding new one's I wouldn't try either.
Good point on the 29. If you want a single clown I would go maroon. However if you only want clowns in the tank, a pair of percula or occ would give you more eye appeal
How old is she?. I have my 18 yo feed when I go on vac. I still fear a death toll lol. I pre portion the food tho in individual bags. She justs thaws and feeds
