The Pros and Cons of a Bare-Bottomed Marine Tank

bare bottom tank1 The Pros and Cons of a Bare Bottomed Marine TankIf you’re in the process of planning and setting up a new saltwater aquarium, you’ll need to give some thought to the type of substrate you’d like to use. It may seem counterintuitive, but one of your options in this area is to dispense with any sort of substrate altogether and go bare-bottomed (BB). To help you decide whether the BB approach might be right for you, here are some of the pros and cons to consider: Pros: Very easy to vacuum up uneaten food, fish waste, and other detritus that has settled to the bottom without siphoning up sand in the process. Allows you to aim the effluents of powerheads and other sources of water movement in any direction desired to maximize water flow throughout the system and behind rockwork without creating an underwater “sand storm.” Detritus more readily remains suspended in the water column so it can be filtered/skimmed out efficiently. Cost savings from going sans substrate can be significant depending on the size of your system. Cons: Arguably less natural looking, though this is a matter of taste. (Plus, coralline algae and, potentially, various encrusting invertebrates will eventually conceal the bottom, giving the system a more natural look.) Can’t keep burrowing fishes as easily. Some BB aficionados get around this by placing a substrate-filled container somewhere in the system. Having no sand-dwelling microfauna can mean lower biodiversity More: The Pros and Cons of a Bare-Bottomed Marine TankMore:

Earthquake In Napa Devastates Local Fish Store


Sunday’s 6.0 magnitude earthquake in Napa Valley, California had devastating effects for the surrounding community. With reports of up to 1 billion dollars in damage, the earthquake, which was the largest earthquake in the past 25 years, effected many businesses. Napa Valleys only aquarium store, ‘Aquatic World’, took quite the hit. Of the 150 tanks in the store, most were shattered in the quake. The scene that awaited the owners was disastrous, the aftermath left fish and tanks all over the shop floor. The owners worked for hours after the quake to try and save the 100 fish or so that survived by getting them to another location with working tanks. Here’s hoping for a speedy recovery for Aquatic World and its fishy inhabitants. MOREMore:

Orchid Dottyback: Hardy, Peaceful, and Just Right for Reef Tanks

fridmani1 Orchid Dottyback: Hardy, Peaceful, and Just Right for Reef TanksCaptive breeding of marine fishes has been a boon to our hobby in any number of ways, one of which is democratizing access to formerly really pricy species such as the orchid dottyback (Pseudochromis fridmani). While I wouldn’t characterize the current market price of this Red Sea species as “cheap,” it’s definitely in the realm of affordable for most hobbyists—and it’s hardiness, ease of feeding, manageable adult size, reef-friendliness, and relatively peaceful disposition (as dottybacks go, that is) more than justify the modest outlay of cash for a specimen. Physical traits P. fridmani is a small (reaching only around 2½ inches), streamlined fish with reddish-purple overall coloration and blue scale margins. A dark stripe extends diagonally from the snout upward through the eye. This species’ appearance in aquariums can vary markedly depending on the lighting scheme.

Goliath Grouper Eats Shark Whole!

 While fishing off the West Coast of Florida, one fisherman got quite the surprise. While at first the man seem’s very excited to reel in a small black tip shark, the tides quickly turn when another fish quickly comes into the mix to take the catch. Not long after the shark is on the line, does a large fish, what appears to be a Goliath Grouper, come out of nowhere and inhale the shark! The commentary by the fisherman is rather entertaining. The Goliath Grouper is found in shallow warm waters off the coast of Florida and the Caribbean. The fish can reach lengths up to 16 feet and weigh up to 800 pounds. The fish are currently are on the endangered species list. Although its hard to imagine such a large fish being subject to predators, Groupers have been sought after by humans both for their meat and for game fishing, and only recently as the 1980′s have become protected. MOREMore:

Lower Keys Coral Bleaching Report (August 22, 2014)

600stag Lower Keys Coral Bleaching Report (August 22, 2014)
Having been preoccupied with the Miami Coral Rescue Mission this summer, we finally made our first excursion to the Lower Keys this summer on Friday August 22. Sadly, we found that a distressingly high percentage of corals living on the reefs in Hawk Channel are severely bleached. Most of the staghorn corals that we saw were severely bleached or actively dying, though there were a few hardy exceptions. Nearly all of the brain corals were bone white. All over the reef we observed an unhealthy mix of cyanobacteria and algae proliferating on previously dead coral skeletons. Even the normally hardy gorgonians, corallimorphs, and zoanthids showed significant bleaching on all three patch reefs we checked. The water temperature was an uncomfortable 89 degrees on the bottom. Without strong winds or storms to More: Lower Keys Coral Bleaching Report (August 22, 2014)More:

Sleep With The Fishes: Underwater Hotels

These hotels take sleeping with the fishes to a new level. The Manta Resort, recently opened this year in Pemba Island, Zanzibar, it is a stunning property that features rooms located 1300 below the Indian Reef, giving hotel guests the amazing views of it’s rich coral reef. The island is very remote, with the website advising that although the island does contain dirt roads, the only sensible way to arrive is charter flights. And at this point, if you are spending the nights watching the coral reefs from your bed, you might as well through in the charter flight. For approximately $1500/night, you can check into the underwater bedroom. Spotlights are located outside of the underwater bedroom windows, to attract marine life. Not all underwater hotels have to be tropical destinations, on the other side of the World, you can check into the Utter Inn in Sweden. A charming red room in the center of a Lake. Visitors are taken to their hotel room on an inflatable raft. The bedroom windows also feature panoramic views. Once you are in your hotel room, you can’t leave until you are picked up the next morning, so make sure you pack well. Interestingly enough, both of these amazing properties were created by Swedish artist Mikael Genberg, who has opened Genberg Underwater Hotels, with the goal of creating a series of underwater properties. MOREunderwater hotel Sleep With The Fishes: Underwater Hotelsutter inn 300x163 Sleep With The Fishes: Underwater Hotels               manta resort underwater room Sleep With The Fishes: Underwater HotelsMore:
