Actually it depends greatly on the species of fish and how it's introduced to these kinds of numbers. Many fish kept in the hobby will not fair well at all in that kind of soup, especially a tang.runway1 said:According to the Burgess Atlas on fish, nitrates are a low level concern. Fish can easily tolerate as much as 100ppm with no problem. That's from a published marine biologist.
As for too much too quick, we're only talking about a single fish here. ONE fish, 2" long in a 55 gal.
As for parasite possibilities, definately a concern. If you have been introducing new fish after one has died of unexplained causes without a proper fallow period, you end up continuing the life cycle even though the new fish is otherwise healthy.
You should allow the tank to go fishless for about 6 weeks. This will allow you the proper time to set up a QT and the parasite(s) if any in the main to die off. While the fallow period is ongoing, you can QT the next fish and straighten out any water quality issues in the main tank. Be sure the main is fed every few days to keep up the bacterial levels.
