Marine Topics - Water Quality
It would be true to say that the majority of aquarists never test for dissolved oxygen (02). Nevertheless, oxygen is an extremely important gas and essential for the survival of the vast majority of livestock that we keep. This is, of course, most evident in fish, which draw oxygenated water in through their mouths, passing it over oxygen extracting membranes within the gills and expelling the depleted water out through the gill slits.

Marine Fish - Angelfish
Like most other marine angelfish this species is another true beauty. One could say that it runs in the family. Adult and juvenile Majestic Angels (Euxiphipops navarchus) also known as the Bluegirdled Angel differ greatly in coloration. This above pictured specimen has begun its transformation into the adult color pattern. A complete juvenile has no orange color at all and the electric blue bands extend into the dorsal fin. The adults are bright orange with many blue dots in the mid-section of the body. The dorsal fin and tail are fireball orange with an iridescent blue border edging. Its face also turns bright orange from below the eye and extending along the gill plates towards the anal fins.

Marine Invertebrates - Invertebrate Systems
Newcomers, beginners, novices, call them what you will, are the lifeblood of our hobby. They are often confused and discouraged by the ‘rocket-science’ offered by hobbyists at the other end of the scale (and THEY were all newcomers at one time don’t forget!). This is a pity, for without fresh input, our hobby would soon start to decay!
If you are new to the marine fishkeeping hobby, I offer you a personal welcome and will do everything I can to make your transition to experienced enthusiast as painless as possible. If you have not already read the FAQ’s page then you will find plenty of basic information there to think about.
