Hey , the tangs can be pretty aggressive , mandarins most preferred foods are live tiny crustaceans , angels cannot be together they may not do it at first but they will eventually and damsels are really aggressive
As 2quills say that most of them won't last long but maybe it just found a good spot waiting till food grows . I know a friend that has starfish and they last a bit but they just die off
When I was searching my old pictures when I was a baby I saw that in the beach I go the tide was way higher and there was a lot of corals . But now when I go there there is nothing and it took me sometime to guess we're did they go . And suddenly I look at the floor all there is is the limestone...
Yellow tangs like their space...6 foot of it. When they are in a tank not suited, they get really mean to defend it as all their personal turf...all SW fish generally are very territorial.
I know that yellow tang is super aggressive even more aggressive than a clown or purple tang
They are easy to tell the difference when you look at the head, can't miss those pinchers. I read what you did too...an hermaphrodite still needs a mate. I also know they will over populate if there is...
It wasn't a bobbit because if you look close enough you can tell them apart . The goby was injured because he started fighting with my yellow tang and it hid in a rock and the bristle trapped him and started eating
