No problem with me. I've had good success with Copperbands, too. As long as you get them to eat well, they are fine. I even had mine eating dry food (freeze dried mysis and zooplankton). And that tank size is fine, too.

But there are others here that do not agree, as you will see...

ummm you havent seen my tank have ya lol :P

go for an island style aquascape or something that allows the fish to swim a full circle without hitting a wall and i think youll be just fine:)

Tank size with a copperband really has nothing to due with their success. Getting them to eat is the success! lol.

WORD. If you have 4 X 3ft walls in a criclular pattern for them to swim in, they'll be happy as a pig in $hite

In my reading, it has been pointed out that cpb's don;t eat mysis in the wild.
They are omnivorous but their diet consists mostly of micro flora (and some fauna) so even when they are eating frozen, they're basically living on mcdonalds.

Thats why so many reputed to be eating frozen foods still die from malnutrition.

Hate to be a devil advocate, but what is the minimum tank size length wise for a powder blue tang? is it 3'x3' , 2'x2' or 1'x1' if someone have nothing in the tank but water and the fish? Couldn't the fish swim around in a circle in a 1'x1' tank and not hitting the wall. :twised:

It's fine for a copperband, the problem is the copperband itself. Many die because they don't eat or won't eat enough. I had my copperband in a 75 allons for 2 years and he was fat as a little pig. He ate live white worms as his main diet for all that time. I sold him because he was starting to nip at my clams and corals, so this is a risk. He was fine for 2 years.

Why do you want a copperband? hope you know they are very finiky eaters and you might have to give it some live food and messy food like fresh live mussels. They often have problem feeding because they are gentle fish and other more aggressive fish will get to all the food before the copperband even have a bite. They are way best kept in a tank with no aggressive fish at all. Mine was with one niger trigger that was always hiding, and just a few small fish. I was feeding him twice a day with a pipette so that he would eat. They can be very time consuming and you must be prepare for this.

if you read his thread youd prob see hes had a copperband for a while now he just wants to know if the tank size is good or not;)

at what point does 1ft , 2ft or 10ft make a difference to a fish that swims a sq kilometer a day?

interesting...I agree that 1ft sq, 2ft sq or 10 ft sq doesn't make a difference to a fish that swims kilometer sq. But somehow my gut feeling tells me putting a powder blue in a 1'x1' tank is not a good idea.

Tangs are swimmers. They swim to and fro and need the length that larger tanks provide.
Anyone who has had a 3 or 4 footer can attest that the longer tank is more suitable for tangs. I think you know that.

Like almost all reefers I have not been able to keep a CB lontg enough to determine their spacial needs.
