Now, before you scold me for tank size, just let me tell you that once the fish seems to be too big for it or has stress, my lfs will trade it for a juvenile butterfly fish, which is all I will ever get. They originally said to get a large fish to have bioload, and I was looking into tangs. however, the ones I wanted I asked them about, and they recommended another Tang, which I don't really like. So, I started looking into other fish, and I saw at their store a Copperband, and I thought that would be good. I am going to get some springeris from them in a little bit, and I will ask them about a copperband. If they say it's not a good idea, I will switch to a tomini Tang. My tank is a red sea nano
