Sophie Payne –
The Dusky Wrasse has been in my 50-gallon reef tank for six months. It’s active and helps clean algae from the rocks. I noticed it’s semi-aggressive but doesn’t harm other fish when given space. Good for a reef setup with proper tank size and hiding spots.
Jessica Martin –
I added this wrasse to my tank after researching compatibility. It’s healthy and active, though it does chase smaller fish occasionally. I’ve provided plenty of rock cover and it seems to be adjusting well.
