I'm certainly not telling you not to get one, they are beautiful. If your friend has one, then at least you have someone to get advice off. Always remember, it's your tank, so your choice of stock. Others can only give their opinion but it's you that ultimately looks after the tank. A great tip is to research your stock and NEVER impulse buy, no matter what the LFS tells you. Some LFS give out crazy advice(which you'll see on this forum) but others give out great advice. Research is the best way to keep/maintain a happy, healthy tank. Nowadays that's so easy and can be done quite easily in the LFS store, use your phone!!
