I love the blue tang! It is very easy to keep and loves eating and hiding into rocks. I have a baby blue tang, this fish is very scared of my other fishes because my they are much bigger than the blue tang. It stays above the live rocks, but it eats!

Very peaceful but will defend themselves. Don't like to float to the top for food. Mine gets along well with a clownfish and a flame angel. No problems. I run a UV on my tank, which I think saves me from Ich headaches commonly associated with this fish.

I bought a pair of regal tangs. Great fish - super colours and constant movement. At one stage they looked a bit sickly with Ich, but improved water and the UV must have helped. Always active. A great buy. One of the pair is larger than the other - I hope they are both eating equally. They seem to get on well.

Blue tang is no doubt one of favourites for reef tank. I have 4 of them in my 300 L reef tank right now. Don't have much problem with them for 6-7 months after I've tried it for a few times. They are not easy to keep, especially if you want to keep more than 1. Best suggestion for people is to purchase at least 4-5 small blue tangs (3 cm) if you have the space (at least 300 L) and money for them. They grow in size relatively faster than most other reef fish. Before you put them in - have some cleaner shrimp in place. Make sure you put all the blue tangs in together. Otherwise they get really stressed if they have to keep readjusting to tank mates. After you put them in, the first week I called it the Judgement week. If they don't have white spots or rotting then consider yourself in luck. If they do...then you have to watch them closely, because if their situation is worsened they will die slowly. You would have to make a decision whether you want to take the ones with white spot/rotting out of the tank to medicate it or leave it in the tank and pray for it to get better. BTW, I don't find UV too helpful, because white spot are usually the result of stress - lowering immunity (less slime on the fish scales) making them susceptible to parasites. I hope my personal experience can give people more insights into these beautiful blue tangs.

I've had my Regal Blue for about a year. When I got him he was about 4 cm long, but he's doubled or tripled that size by now. They are not very resistant to white spot and you should always have white spot medicine. When you first by them they will be very likely be prone to white spot disease and catch it in the first few days. These fish have great personalities and for some reason like to pick up shells with their mouths. I've kept my one in my 150 L tank and it seems to be the MOST peaceful fish I have. None of my fish have ever fought with it and not even my yellow tang. They are sensitve to organic matter and I suggest you get a protein skimmer if you want to keep this guy. I also suggest you get a pretty big tank, because they grow big and fast.
