Red Sea Sailfin Tang


New member
Some one has a 12 inch 10 year old SF Tang for sale. I would be adding it to a 310 tank with a 5inch yellow and 4 inch blue tang. I have a 4 inch blue throat trigger as well.

Do you guys think this is a good idea or not? I can't imagine the yellow messing with such a large fish to any extent but I do not have experience in this mix. Right now, all my fish play nice.

If I was going ot worry about it, it would be that the yellow would take a swipe at the sailfin, and then the sailfin would beat the tar out of him.

I have a 8-9" (truly, not exaggerated) RS Sailfin in with a bunch of other tangs (2 Purples, PBT, Hippo, Chocloate). He is a good citizen, but he eats a lot.

My tank is 7' long and he seems a little cramped some of the time. He has a new home coming in a 800G.

They grow fast and it could be way too big for your 300, if you feed it appropriately, in a year or so. If you don't feed it very well, then it will likely get VERY agressive towards your other fish.

I think that the fish will mix, but your tank is just a temp stop for the fish IMO.
