Blue tangs are they hard to keep or not???

a 40g is fine for a 40g as long as when it gets a bit bigger it goes into a bigger tank.i know people who have done this with no problems at all.

 

I added a yellow tang about 2 weeks ago and he is doing great. Love the fact that he eats all the algea but make sure you supplement with Nori or seaweed. Planning on getting a blue tang and initially thought about a powder blue but read that they have problems with getting acclimated and will most likely die after a couple of months.
Good luck and all the very best to you

 

I picked my blue up at about the size of a quarter. I have not had (knock on wood) any problems with ich since I got him. He is about 7 months old now He will be joining the rest of the tank in a 120g soon

 

That very interesting you can start a thread wondering about Tangs and only a few posts later you can begin giving advise.

 

im only giving advise on what ive heard and anyway my thread was about if they are hard to keep not on the size of tank they need..

 

I had a blue and yellow in a 55 gallon for 2 years without any problems. Finally had to give the blue up because he was getting to big. But during the 2 years I had him, he was great and love to swim back and forth in the front of the tank like a madman when I was near by......He may have been showing off

 

The size of the tank that they're kept in has a direct affect on whether or not they can do well. So, if they're kept in too small of a tank, regardless of the size of the fish, they can suffer as a result and get sick. This will make them hard to keep. If you're going to upgrade soon, why not just wait until you have a bigger tank to get the fish?
