Sick fish?

[Animal-Chin]

really hard to tell from the pictures but I have 2 thoughts.

1 - Something is agressive and biting the fish causing wounds? When you add 3 fish at the same time and they are all the same species they may be fighting for territory.

2 - They have ich or some parasite and its causing them the flash against rock which is hurting their bodies.


I'm guessing your fish that hid then dissapeared may be a goner. I've had wrasses not take to acclimation before and the minute they hit the tank they hide never to be seen again...
