QT experience - Aggression

[Brutus]

Hello all!

I’m a year into the fun that is my marine tank tank hobby and it’s been quite the learning curve with my 200 litre tank.

I rolled the dice and went ahead without a QT (idiot) starting with a tank of 2 clowns and then Slowly introducing over the year a Royal Gramma, Blenny, goby and finishing with a Six Line Wrasse as my final fish. Over the month, they’d all got on well… when I noticed a sugar like coat on my clown (I can spend ages trying to place blame on who carried it in and point the finger but will never know…. But….looking at you, Six Line)… within a few days he was dead and as I scrambled to get a QT up and running, the Royal Gramma started showing signs of rather than the slimey and sugary appearance of the clown, these larger circular discolourations and a sticking to the wall in slower movements. He came solid and good for a week in the QT after a Hydrogen Peroxide bath and a week later and before I could treat showed the symptoms again and within that day had died. I still believe that brooklynella was the culprit (local fish shop seemed to indicate that it was, see attached pictures) and have since treated the remaining 1 clown, Benny, goby and Six Line with metroplex and they look and act great.

So my questions are;
- (maybe should be in disease forum, sorry) I’m weighing up a copper treatment to treat velvet as the other potential culprit. If after what is now 2 weeks without symptoms, do I bother?

- That peaceful Six Line has turned into a jerk in the 50 litre QT against on occasions, his tank mates. This wasn’t completely unexpected as they were placed in at the same time. So when the fallow period is up and I’ll reintroduce into DT… how best might that be managed? Leave Six Line alone in QT for extra 2 weeks etc?
How might I introduce a new clown and another likely tank mate with the Six Line?

Sorry for the mouthful of questions! Trying to think about how I can re-establish my previous tank harmony because I enjoy watching that Six Line when he’s not now being an occasion jerk in the QT where he wasn’t in the the DT.

Thanks all!

a 13 gallon tank is very small for qt for 4 fish, especially if one of them is a 6 line, qt tanks usually have no rocks, so the aggression is understandable.

Thanks for the reply mate.

Agree and I think that is the cause of the aggression, being only 13 gallons. It sucks they’re in there but I’m working within what I have I suppose for the time being. Also, to the Six lines’s defence, I’ve only witnessed the aggression on occasion as the clown and Blenny have picked their corners with enough pvc pipes to call their own while the six line cruises about.

My thoughts were looking towards their reintroduction into the DT… how best to manage that…

The pictures are too blue for any definitive diagnosis, but given the time frame here as well as the described symptoms, I'd say this was Brooklynella, not velvet. Copper won't work against Brook.

Yeah apologies for the photos. Strange thing, was harder to see that sugary coating without the blue light on the clown. You might on zooming into the tail of the Royal, see a large white discolouration. That was present also across his body.
I hope following some direction from Humblefish that metroplex does its thing with the Brooklynella. ATM, no symptoms with the other fish have shown themselves.
