How many fish can I add at once

[FRANK48]

I have a 50 gallon tank with six fish and I want to add 5 more fish at once. The tank has been up for more than a year now. Is it okay to add 5 fish at once or is that too much.

It can really depend on the current fish you have and the ones you plan to add. Generally, with one fish at a time it's easier to deal with potential conflicts between fish. You also gradually increase your bio load instead of hammering it. But again, it depends on the fish.

Goby should be fine. Lawnmower blennies need *lots* of algae, and I have a hard time supporting mine in a 160-gallon tank (so just a heads up). Chromis should be fine - but they need multiple daily feedings to stay out of trouble.

The clownfish should leave most of these additions alone (no guarantee, though).

Okay thank you. I currently have some hair algae in my tank so the lawnmower should have a feast

Maybe. They can also be very picky with their diet.
