Yes I know that they are tricky but the ones I have try before was never eating - these eat constantly. We will see what´s happens with the one left,
Could be in the long run - Najers 3 month - but not in my case - too fast course of events IMO. I still believe in some type of accident - the fish have been trapped between stones or something like that.
A would avoid the wrasse (too much a swimmer and it get around 12 cm), the hawk fish (to large and exclude shrimps (20 cm) and the bicolour blenny (too aggresive)' Another suggestion 2 A.clarkii; 1 yellow banded opossum wrasse (or any other opossum wrasse from the genus wetmorella). Two smaller blennies from the genus Emblemaria and 1 or two hawk like anthias from the genus Plectranthias They eat small shrimps but the larger one use to work good
bicolors are more agressive then clarkii? mine lives in his conch shell and never leaves it except for food or to move away my hermits away from his algae.
. Personally - I have 3 small percula in a 20 gallon and it has not been any problems with them and other fish, I had a bicolour blenny in my 80 gallon aquarium - and he/she rule its part of the aquarium.
