Fish Are What Fish Eat!

Aquarists have a wide variety of fish foods at their disposalWith so many fish foods on the market these days, it is really difficult to know exactly what your fish are eating. They will chow down with gusto pretty much anything you put in the tank, but do we really know what is in their foods? When we go to the market, I am sure the majority of us read the labels to see what we are ingesting. But is it the same for fish food? Usually not. Fish food labels provide a breakdown in protein and amino acids, etc., but we don’t know the exact ingredients since the FDA does not regulate fish food. Take dogs and cats for example MORE

Texas State Aquarium Accidentally Kills 100 Fish

 In an effort to combat a pesky parasite that was harming the tanks, the Texas State Aquarium accidentally killed nearly 100 fish. This is very rare and upsetting incident. The parasitic flat worms in the tank were resistant to other treatments, so on Monday the Aquarium introduced a new medicine into the ‘Islands of Steel’ and ‘flower garden’ exhibit tank. The medicine killed all of the fish except for two. Many sharks also perished. MORE

Even now, do Moorish Idols remain impossible to keep?

DSCN0924The Moorish Idol has eluded aquarists for a long time. It’s interesting, because idols aren’t particularly rare, exclusive or expensive fish. In fact, when compared to many common marine fish, they can be purchased relatively cheaply. Perhaps this fact works against the idol, as their low price makes aquarists more likely to experiment with them. Moorish idol survivability in private marine aquariums couldn’t be much worse. While some idols do survive in the hands of experienced aquarists, (and by some I mean a tiny percentage) the vast majority imported into the trade perish, even under the best circumstances. Many outlets no longer import Moorish idols, and years of utter failure have made many aquarists ask the question if they should be imported into captivity at all. Are Moorish idols truly impossible to keep? What separates them from the masses of marine fish that can adapt to captive life? Should even the most advanced aquarists shun the idea of keeping idols altogether?  MORE

The French Angelfish: Pretty, Curious, and Well Worth the Tank Space!

Adult french angelfish (Pomacanthus paru)One of my more enduring memories of diving in the Florida Keys was coming across a pair of French angelfish (Pomacanthus paru) gliding in unison above the reef. Unlike so many other fishes that dashed into hiding as I approached, the angels actually swam right into touching distance and seemed to take an interest in my presence. Whether they were naturally curious, accustomed to being handfed, or just amused by the sight of such a big fellow squeezed into a wetsuit, I can’t say, but their beauty and boldness certainly impressed me. If you happen to have a system large enough to accommodate one of these angels, I don’t think you’ll be disappointed either. Let’s look at their characteristics:Physical traits Juvenile Pomacanthus paruFrench angels aren’t as spectacularly colored as some reef fishes are, yet they’re subtly beautiful nonetheless. Adults are bluish-black overall with golden-yellow scale margins. The face is slate blue, the mouth is white, and the eyes are rimmed with gold. As with many angelfish species, juvenile French angels differ considerably from the adults in coloration, being black overall with five vertical, curving yellow bars on their flanks MORE

Dr. Sanjay Joshi Delivers New Photon Hybrid (just don’t air ship them because we all know how that goes)


Juvenile Half Black Picasso Photon (Hybrid)

 Meet the newest member of Sanjay’s Photon Clownfish family tree – The Half Black Picasso Photon! A true love story for the ages, the Photons all stem from a rather licentious female Onyx Percula (A. percula var. Onyx) Dr. Joshi picked up along with her chosen mate, a Black Ocellaris (A. ocellaris var. Darwin) in Colorado he dubbed “The Odd Couple”. Following the first unexpected spawns in 2009 that resulted in the handsome hybrid, the Black Photon Clownfish, and the loss of the original male, the female was paired with a subsequent string of suitors (a few of which were fated to murder). Sanjay threw us another surprise when the frisky female successfully paired with her own progeny in 2011, bringing us the Half Black Photon and, more excitingly, proved that the hybrids were indeed fertile (you can read a bit more about the history here). It’s been a while since we’ve since seen anything new on the Photon front, so we’re pretty giddy to announce the most recent spawning of a male Bali Picasso and a female Half Black Photon! MORE

Charges Against Mother After Boy Falls In Cheetah Pit

 The Cleveland Metro Park Zoo is in the spot light for one Mom’s ridiculous behavior. An Ohio mom is being charged with misdemeanor child endangerment after her two year old son dropped nearly ten feet down into a Cheetah exhibit from the viewing deck. The mother was allegedly dangling the boy over the exhibit rail. The father was also present, but is currently not being charged. The parents went into the exhibit and retrieved their son without any interaction from the two cheetahs residing at the zoo. MORE

Write-Up Wednesday: The Recirculating Protein Skimmer

A protein skimmer provides mechanical filtration by removing organic molecules from your saltwater aquarium’s water. And a  recirculating protein skimmer differs from other protein skimmers in 2 main areas: 

  • the water depth required for the skimmer to operate
  • the number of pumps that run the skimmer

Water Depth Non-recirculating protein skimmers have to be run inside of your sump or tank and they all require a specific water depth to operate. (The exception is hang-on back protein skimmers which hang on the back of your tank or sump). Usually there is an acceptable range between 7-9″ (18-22 cm). Recirculating protein skimmers, however, do not require a MORE: Write-Up Wednesday: The Recirculating Protein Skimmer is the world's leading destination for sustainable coral reef farming and the aquarium hobby.
