Captive-bred Yellow tangs move one step closer!
10/31/15 Difference in spines Yellow Tangs Hi, A few months ago, I found an article on the web that said the size and bright white color of the spine at the base of the Yellow Tang's tail indicated the sex (of course, I can't find it now). Is that fact true (or is there anything that indicates the sex)? <I think this is not factual... have dived with large Yellows (in Hawai'i) and seen individuals (about plate size) that appeared to be "full of eggs"... their caudal peduncle spines are not different in color> If so, we may change our plans to add a Hippo and add a smaller second/female Yellow instead (if it is true, ours is a male). We have not been able to quite decide if even our 6 foot tank is indeed big enough to keep a hippo happy as an adult. <It is> It sounds like they like to swim distances and the Yellows are more grazers? <I do agree with this Zebrasoma tangs period are roamers... the Paracanthurus stay in about one area> Also, if sexing the Yellows isn't possible - would a smaller Purple work (I thought it was an absolute no, but have been reading recently that if the Purple is smaller and they are added together it would work)? <Should work out fine in this size system... some jousting, chasing at first, but not likely any real damage> We will take your advice and scratch the Yellow Eye as a possible choice with the Yellow. Thanks!! Debbie <Welcome. Bob Fenner> BREEDING YELLOW TANGS? Do yellow tangs breed well in home aquariums? What are the signs? <They don't breed at all in the home aquarium. James (Salty Dog)>
