All water parameters were good, even the salt density!
Two days ago I put AntiRed in the Aquarium due to Red Algae, afterwards I a part of the water and removed the dead red algae.
Today the fish was spinning around in the water, it seemed pretty weak and didn't want to eat.
Let's say it looked disorientated.
Was it sick? What could've caused it because it never looked sick before!
Thanks!
