How many fish am i limited to?

[brandon101996]

so i have a 75 gallon DT tank, about 3 months since start up. i already have a full CUC and as far as fish go i have one green chromis, one chalk basslet, one flame angel fish, and one stripped blenny. i want to add corals in a few months but was wondering what’s the max amount of fish i can have in there. i will be adding a high and 2 clown fish in the next week also

Welcome to Reef2Reef!

Carrying capacity of aquariums are difficult to calculate because there are so many variables: how large the fish will grow, will they fight, how much rockwork is in the tank, filtration type, how often you do water changes, etc.

Your tank has room for a few more fish.

I wrote an article that addresses one aspect of this - the need for swimming space:
