The Petite, Pugnacious Atlantic Pygmy Angelfish

Atlantic pygmy angelfish (Centropyge argi)Having very recently departed the state of Ohio and resettled his family down in the Florida Keys, Caribbean Chris has had to part with his beloved, long-established Caribbean-biotope tank. He’s also had to come to terms with the reality that the specimens he bequeathed to me are now gracelessly intermingled with my Indo-Pacific species. So, to give CC a little inspiration (or torment his soul, either way), I thought I’d dedicate today’s post to a fish species that might be a welcome addition to his new tank whenever he gets around to setting it up—the Atlantic pygmy angelfish, aka the cherub angelfish (Centropyge argi). A denizen of the tropical western Atlantic and Caribbean Sea, this dwarf angel is a visual gem and can be a good choice for smaller systems. It is, however, rather feisty for its size, and this trait must be factored in when choosing tankmates, contemplating order of introduction, etc.Physical traits C. argi is blue overall with varying (by individual) degrees of orange-yellow coloration on its face and throat. The eyes are ringed with blue, and most of the fins (with the exception of the pectorals, which are yellow) are very dark blue, almost blackish, with lighter blue margins. Typical of marine angels, this species also has sharp, backward-curving spines on its gill covers (which are prone to getting tangled in nets).

Pink Longsnout Seahorse on a Gorgonian

Good morning from Curacao. I get a lot of mails asking for more seahorse photos so like a good little diver, here you go! This little pink beauty was found at a dive spot called “Small Wall” and to this day is still one of my favorite spots to explore. This is normally a boat dive but for those of you willing to throw a little caution to the wind it can be done from shore, here’s how you do it. Drive to Directors Bay, set up your tanks and walk down to the beach and remember not to leave anything of value in your car as it most likely won’t be there when you return. From the beach head south-east (on your backs at the surface) following the curvature of the reef wall from Directors bay.

Understanding Old Tank Syndrome

In a few years, my reef will turn 50 years old. I believe I’ve avoided old tank syndrome by using the procedures outlined in this article.Old Tank Syndrome, or OTS, is something we have been hearing about since the hobby started, and I am not quite sure exactly what it means. Is it due to parameters, loss of diversity, lack of interest, diseases, metal accumulation, global warming, locusts, or all of the above? I think it is much simpler than “all of the above,” but some of those things are probably on the list of causes—especially locusts. It’s about bacteriaIn my opinion, OTS has to do with bacteria, or lack of it. Bacteria really run our tanks, and we are just there so the bacteria have something to make fun of. Without bacteria, our tanks would crash in less than a day.
