Nitrous - Hello. Furcifer are a great Tang to keep. Firstly I would like to state that if you have not kept many Tanganyikans, make sure that your Furcifers are atleast F1, wildcaughts can be very tricky to keep.
Having said that these are not the most demanding fish. As with most other fish, good clean water quality is the key. A pH of 8.0 - 8.5 is prefered. This fish can also get some decent size, I have personally owned a few males in the 7-8" range with all their finnage.
Be selective with tankmates. Some mismatched tankmates will make short work of their most beautiful assets, their long streamer like fins.
any other q's, i'd be glad to hep with -
Alex
