Trouble with Tangs

[Dkuhlmann]

Ok so what about a Purple tang? They're pretty aggressive and I'm sure not going to let the PB pick on it.

IMO the title says it all: tangs cause nothing but trouble.

Are we really surprised at the responses when at the top of the page it states a minimum of 240g for a sailfin? The people replying are correct and the way fish are introduced in what order , play a huge part in compatibility

 

[nikon187]

Many things work when attempted but long term is the goal here. Ie 10-15 yrs with this fish

Compatibility with the powder is up to the powder.. I would say that is his tank now territory wise and any other tang will be a threat. It's whether he subsides is the question and only the fish will tell you that

Following up, I removed the eggcrate divider after 6 days. After one day, the tangs haven't even acknowledged each other's existence. They're both eating and active. So far, I'd deem the egg crate a success.

Assuming sensible choices, the most important thing in successfully adding another tang to an established population is to make sure the new fish is as prepared as possible to withstand a few days of 'hazing'. Asking a just-bought, journey-starved fish to survive this is asking a lot. Do yourself and the fish a favor with a couple of months of QT to get it settled and fattened up. I've added, sequentially to my 265 with resident yellow and regal/hippo, a Purple, an Achilles, a Desjardini Sailfin and just this week a Chevron. The sailfin was bigger, but all the others were smaller. Some initial aggression, but all have survived. My only loss was a Naso that got chased and pinned onto my vortech.

I agree. It's definitely not a good idea to throw a weak tang into a tank with established tangs. However, this fish had been quarantined and was fully healthy, this was a total territorial dispute. The sailfin wouldn't have just been hazed, he would've been murdered had I not separated them.

The separation with the eggcrate did wonders. I'd encourage others to try it if you're stuck in the same situation.

Marine Ich getting so strong to a point where it could wipe out your tank depends on various factors such as salinity, temp etc but I think one of the most important factor is the HOST fish. Tangs are bad news. It will help get ich very strong very fast and make it a ich bloom and wipe out all the fish in your tank. That being said I have a tank full of all kinds of tangs. Without ich though. lol

I have a goldrim tang aka white cheek, A. Nigricans. Powder brown aka white faced is A. Japonicus older books often confused the two such as the Marine Aquarist by Robert Fenner; check http://fishbase.org/summary/Species...igricans&AT=acanthurus+nigricans&lang=English .... I added my Achilles and goldrim to my 240 at the same time and the goldrim was the boss after about a week of competition so I had to pull it. Not sure If want to put the goldrim back now that the Achilles is established and swimming elegantly. In there also are 3 yellows, sailfin and naso. I may try separating them with eggrate or just keep the goldrim in the frag tank. Tangs are PIA
