How many fish is too many? Tank Stocking

[Myka]

The fact that you have to use bio pellets to keep nitrate down, and it's still at 5 to 10 PPM, shows that your tank is already stocked more than it can handle. Maybe your skimmer isn't big enough or good enough, or your tank is too young, or you're not cleaning it good enough, the system can't handle it.

The biopellets have been online since the tank was filled. skimmer is BM7.
I do spend a lot of time with the tank and do keep it quite clean.

When googling around the advice and opinions vary greatly, just wondering what other reefers here think.

Thanks

The reason why the answer varies is because there are so many variables that contribute to this answer. You can put as many fish in a tank as your tank can handle. What your tank can handle will depend on how proficient you are with maintenance which includes but is not limited to: cleaning, nutrient export, feeding, behavioral (stress, aggression, etc) control, and so on. You already know that all of these things need to be a balance for a healthy tank. The more fish you add the more challenging it will be to control/balance the other variables. This balancing act differs from tank to tank, even among tanks of the same size.

So, the answer to your question is: whatever number of fish you have that puts your tank out of balance is too many fish. Probably :-)

adding the hippo tang will massively increase the bio load as they are big fish and a full grown one should not even be in a 90 gallon.

the foxface is a large fish with a big bio load as well

i also see you have 4 clownfish, are they mature? it is VERY rare to see them all get along, chances are you will end up with 2


and 2 mandarins in a 90 wont work, even one will destroy the pod population in your tank, a mature 90 can support one though

The 4 clowns all came from the same batch of fry. They haven't shown any aggression yet and are always together in a ball. Maybe when 2 decide they will be a pair there will be fighting but nothing yet.

Both of my mandarins actively chase down and eat mysis, and have fat bellies.

The question being asked is tank stocking levels, not compatibility and feeding requirements.
