It's all in the lighting. I've got 4x 54watt T-5 HO's on there with two actinic bulbs (which are blue...) and two daylight bulbs. When you have a lot of blue light, blues really stand out.
Great looking tank Jamie, we need to do a wood collecting trip this summer I like yours a lot. The H. carpintis are looking incredible. I wish you luck with them. I really wanted to keep them but my festae would not allow it so I'm glad they went to you. That male is going to be a stunner... I liked him the best and got rid of the rest.
Thanks again for helping me move my 300g and 120g to the new house today. Hopefully next time your over we will have time to mess around with camera gear.
