ok to add fish?

[moo0o]

i want to add 3 snails 1 cleaner shrimp and 1 tang at once, is this fine?



my parameters are

undetectable ammonia, nitrites, and nitarates.
salinitiy is at 35ppt
however my calcium level is at 350ppm and my alkalinity level is at 15dkh.


do calcium levels and alkalinity levels like these affect the survivability of fish and inverts?

Ordinarily no. Since this is your first additions I would not do it all once. Also, I am not the Tang police, a tang in a 55 gal tank probably will not fly. Add some snails and maybe some crabs. Most people start with cleaner crews anyway.
