    Predatory Isopod

    Aiptasia polyp

    I found this baby Aiptasia polyp on the glass panel of my new reef aquarium. Very cute up close, just sad this is such a hated pest in our aquariums. 20140214-20140214-DSLR_IMG_0001.jpg by pwnell, on Flickr Aiptasia polyp, 4x*1.6, POL 20140214-20140214-DSLR_IMG_0024.jpg by pwnell, on...

    Tropical aquarium surface film bacteria

    Without surface skimming, a tropical aquarium (especially if CO2 injected) quickly develops a surface layer of bacteria. This layer prevents proper oxygenation of the water, which can be harmful if the tank is not planted heavily enough. Here are some closeups of exactly how this layer looks...

    Cardinal

    Most people think of a cardinal tetra as something with red and blue stripes. When using epi-polarization, one gets quite a surprise. 20131010-DSLR_IMG_0733.jpg by pwnell, on Flickr Cardinal, 20x/0.45,EPI-POL+POL, HF B 20131010-DSLR_IMG_0698.jpg by pwnell, on Flickr Cardinal...

    My tank

    Here are two photos of my tank I took using fluorescence. Some coral died off, some started growing wild. It is a dynamic system that has ebbs and flows just like real nature outside I guess. This tank has been up and running for 2.7 years now. I always thought I did something wrong...

    Euphyllia polyp

    Aiptasia under full colour fluorescence

    I have not manipulated any colours other than to excite the Aiptasia with UV and Blue light. This is all auto fluorescence.
