A Fishy Biology Lesson From Paul

pipefish biology 300x169 A Fishy Biology Lesson From PaulThough fish are our distant cousins, there are more differences than similarities between us. In today’s post, I’d like to explore the various characteristics that make a fish a fish—or not. Skeletal distinctions Of course, not all fish are the same and the oldest fish are not truly fish. True fish have bones somewhat like us, but not exactly. All of our bones are connected together by cartilage, but in fish, the fins are not connected to anything but muscle. The tail is connected to the spine, but none of the other fins are. Sharks and rays have no bones, only cartilage. Built-in buoyancy compensators The swim bladder in most fish (but not all) allows them to maintain neutral buoyancy, or the ability to stay in one place in the water without sinking.

Yellow Tang… so close, yet so far… – Update from OI

yellow+tang+Day+60+001+7x Yellow Tang… so close, yet so far… – Update from OI Since we last wrote at Day 50, we’ve observed a lot of interesting things with our yellow tang larvae. Probably the most important thing we observed is their very inefficient feeding capability. At their size (~1cm), newly hatched Artemia nauplii should have been easy prey, but time and time again we’d watch them strike and miss, or partially catch one only to spit it out. Artemia nauplii definitely don’t seem to be adequate to sustain yellow tang at this stage in development. Likewise enriched Artemia were all but rejected. Also, at this stage, the fish seem to rely on their large pectoral fins for propulsion and were very awkward moving around the tank.  We would frequently observe them floundering about and then suddenly right themselves and swim on quite normally. This seemed to require a lot of energy, which in their compromised nutritional state, likely lead to some additional stress. They also tended to gravitate MORE:Yellow Tang… so close, yet so far… – Update from OIMore:

The Polyp Craze, a Look at Why Zoanthids and Palythoas are So Popular Even After All These Years

29f9reefkoi14 1024x833 The Polyp Craze, a Look at Why Zoanthids and Palythoas are So Popular Even After All These Years
In this hobby we see coral and invert phases come and go. From clams to chalices and even maxi mini anemones, it seems like they all go through a lot of initial hype then slowly decline in popularity. One of the mainstays in the hobby have been zoanthids and palythoas, which have been the craze for quite a while now. They have been in demand for what seems like an eternity and they do not appear to be getting less popular. Instead, it seems like they’re constantly on the rise. Zoas and palys are highly favored in the hobby by both beginner and expert reefers alike. They don’t require much in terms of care like other specimens and they grow under many types of lighting from T5s to LEDs. Polyps grow at the bottom of the sand bed or on your highest rock. They don’t necessarily need to be target fed like other corals and they also do not require us to dose things like calcium.

Playing with the Ecoxotic EcoPico

0369EcoPico with LED Arm Playing with the Ecoxotic EcoPico Nano aquariums are so much fun. It’s as simple as that. The tiny little glass boxes can be put just about anywhere, and while they can’t house every fish or coral, they can be personalized in so many ways. One such nano that we’ve recently gotten to play with is the EcoPico from Ecoxotic. This tank measures 10”x10”x12”, which translates to just a shade over 5 gallons, and has a small LED light and filter that make it pretty much saltwater friendly out of the box. We have a hard time calling it reef ready, which for the record is not one of Ecoxotic’s claims, but it certainly has a lot of features to get it off to a good start.
