i have a scopas tang in australia they are around $50-$60 how much are they in USA?
They can be very aggresive, but like alot of tangs if introduced with other tangs at the same time they may be ok together?im not really sure. But my tang is very dominant and isnt afraid to use his scapal...(barb) its amazing to see but the sideaffects are not so good, he once killed a cromis by slashing! And the LFS once introduced a yellow tang to a tank where a dominate scopas was residing, within hours it was dead....multiple cuts.
They can be quite plain but given the right conditions a they can look so beautiful, they has blue dots covering their face and up to their gills then their body has blue lines trailing back towards their tail.
They are a heavy algae eater, but will eat anything they are quite a hardy fish, i had an outbreak of whitespot in my tank and he was absolutly riddled with it the whitespot got the better of a blue tang(hippo) and a pair of occelaris! i did buy a cleaner wrasse to help get his better but i really didnt think he would pull through and he did
They are a wonderful fish in my experience i hope i have been of some help.
