For those "duller" looking powder blue/brown tangs.. how many of them brightened up in your aquariums (and how long did it take)?
It seems like they'll be pale when they first arrive @ the LFS, but they still sell then, so im' never around to observe
I have noticed the color of PBT changing to some extent depending on the circumstance.
My PBT seems to be paler in the morning as the lights come on and he get out of his favourite hide out. He darkens within about 30 minutes. His color becomes very dark if he is upset, like when he is chasing other fish.
An update on my PBT adventure: I tried to reintroduce the Scott's Fairy Wrasse and the PBT almost killed him again, so I decided to remove the PBT. I got an acrylic trap from
Here and I was able to bait the fish with nori and finally catch him.
He is now in the refugium andhe is having a feast eating chaetomorpha. I really did not think this was going to be a suitable vegetable for tangs but.... I was wrong since he is iting it.
The scott's is enjoying the big tank and seems happy. I do not know what triggers this passionate aggression on the PBT and specifically against the scott's wrasse.
The trapping process was a game of patience. The PBT is very intelligent. The yellow and the naso very carelessly went straight into the trap and were scarfing on nori. The PBT instead was extremely circumspect like he knew it was a trap. It took at least 2 hours and a lot of nori eaten by the other two tangs before he adventured into the acylic box.
Now I have to decide what to do. I really like this fish and would like to keep him but he is definitely a terror toward the other fish.
I wish I could have something like what Emilio showed us possible with so many tanks coexisting together. My tank is 6x2x2, with plenty of flow. I run a closed loop flowing 3600 gallons per hour with alternating flow from front to back and back to front in addition to approximately 2000 gal. per hour through the sump. Fish are fed heavily 2 times per day. I do not know if I got a particularly mean specimen but I dont know what else I can do to lower aggression.
I may finish stocking the tank then add him last but I am afraid that if I put him back in and he turns mean again I will not be able to catch him again.
I am inclined at this point to ask the LFS to get him back and exchange him for other fish.
What would you guys do if you were in my shoes?
