Larval Rearing of the Purple Mask Angelfish

Larval rearing trials began with the spawning of a Paracentropyge venusta pair in the summer of 2013. The first successful larval rearing trial started with a small spawn on November 13, 2013.  This was the fifth larval run with this species and the focus was on food density and consumption at different developmental phases.  The diet consisted of both cultured copepods and wild collected plankton with all food items being less than 100 microns in size.  To assess consumption rates, five random samples were taken for initial food counts at the start of each test period. All food items added to the larval tank during the test period were counted while maintaining a density of 1 to 2 food items per ml in the water column. At the end of the time period counts were again done to determine larval consumption. At this point a 75% water change was MORE:Larval Rearing of the Purple Mask AngelfishMore:

Video: Jammed In Like Sardines? No Problem With Prodibio

 Normally, transporting maybe one or two fish home from the store is stressful enough (on us as well as the fish), so imagine the challenge if you’ve got to ship 20,000 fish (delicate sardines) all the way from from Japan to Seoul! Luckily Prodibio were on hand in this case to supply some of their wares – Safe Travel (bacteria solution dedicated to fish transportation) and Stop Ammo Pro version (ammo binder which traps ammonia) and thanks to these products, only 6 fishes failed to survive the trip giving it a 99.97% survival rate. That makes us very interested in these products for our own fish transportation needs. More: Video: Jammed In Like Sardines? No Problem With ProdibioMore:

6 Ways to Prevent Photoshock in Aquarium Corals

photoshock coral 300x169 6 Ways to Prevent Photoshock in Aquarium CoralsMany of the corals and other sessile invertebrates we keep in reef aquariums are considered “photosynthetic,” meaning much of their nutrition is produced by photosynthetic algae (zooxanthellae) residing in their tissues. Thus, there is a direct link between the type and intensity of a reef aquarium’s lighting and the health—or even survival—of the corals and other invertebrates it contains. However, it’s very important to understand that corals acclimated to a certain level of lighting can be severely stressed if they’re suddenly exposed to higher-intensity lighting. This commonly happens when: A specimen kept under subpar (no pun intended) lighting during shipping or in a dealer’s tank is newly introduced to a brightly lit aquarium. The reef system’s lighting has just been upgraded, for example from fluorescents to metal halides or LEDs. The hobbyist waits too long to replace aging bulbs or tubes. Dissolved organic compounds that cause yellowing of the water are suddenly removed (e.g., via chemical filtration with activated carbon). So how can you avoid photoshocking your invertebrates? Here are six ways: 1) Research your inverts’ lighting requirements Photosynthetic invertebrates vary widely with respect to their lighting needs More: 6 Ways to Prevent Photoshock in Aquarium CoralsMore:

Blackworms Mean Better Health for Marine Fish

blackworms tank 300x205 Blackworms Mean Better Health for Marine FishLive worms are about the best thing we can feed to our fish. How do I know this? Am I just making it up so I have something to write? Actually, no. Live California blackworms have been used for ornamental fish food since a few years after World War II, as that is when I started feeding them to my freshwater fish. Blackworms will get freshwater fish into spawning condition in no time, and I can attest that the same applies to saltwater fish. Back in 1971, when I started in the saltwater aquarium hobby (I think it was on a Tuesday), I bought some of the first blue devils imported into the US.

Puddingwife, Halichoeres radiatus, Wrasses, Labridae

68dePuddingwife 2 457x305 Puddingwife, Halichoeres radiatus, Wrasses, LabridaeGood morning friends, I have a colorful Puddingwife wrasse for your viewing pleasure today. As many of my fellow divers/underwater photographers know this fish never stops swimming and is very hard to get a photo of. I chased this one for 20 minutes trying to get off a lucky shot and came close to just calling it quits but wasn’t about to get beat by a little fish! Like many wrasses, the Puddingwife goes through a dramatic color/pattern change as it matures, though both the juvenile and adult animals in an attractive fish. The puddingwife wrasse, Halichoeres radiatus, is a species of wrasse native to the Western Atlantic Ocean from North Carolina to Bermuda, through the West Indies and Gulf of Mexico, to offshore islands of Brazil, being absent from Brazilian coastal waters MOREMore:
