That's reassuring. Seems hit or miss with them and aggression. They'll be going into a decent sized tank but hopefully manage in the smaller QT. I'm realizing it's pretty close on the chart with the katherine. There are a few other wrasse that'd be in the process so hopefully that breaks it up a bit.I have owned two naoko fairy wrasses, my first one jumped into the old lid and it was a stiff mesh lid and gave him a spinal injury, now I have another in my nano (Grow-Out) with a blue star leopard and a cryptic sixline, with the old scape on the tank he did flash at the cryptic sixline but it never affected them. Now he just chills on the top of the tank and round the rocks. My favourite fish by far, he did try make it into the sump (He managed it and I eventually got him out). He’s about 1.5” and probably won’t go into my 4’ DT until he’s Atleast 2.5” depending on if he starts to panick in that tank before he gets 2.5”. The blue star will hopefully go into the DT with him, neither of them are aggressive but the wrasse in my DT are supposed to be aggressive (C. melanomarginatus & H. chloropterus) the jade will be gone before they go in though, I would love an Australian Scott’s but fear it would ruin my lovely “pair” of Lubbock’s (Both male variants).
