Salt Speak – Episode 2: Than Thein

We’re back with another episode of Salt Speak! First off, I’d like to thank everyone who reached out with kind words for this new series. It was great to hear the interest in episode 1 and excitement for future installments.In this second episode, I spoke with Than Thein. Than is the owner of Tidal Gardens, a coral propagation greenhouse in Ohio. We discussed a variety of topics ranging from what it takes to grow corals in a greenhouse and how to properly start a propagation business to the state of the reef aquarium hobby and the role of coral retailers. We cover a lot of ground in this chat and I think you’ll really enjoy the discussion. As always, let me know what you think in the comments below. Also, please share this episode with your fellow reef aquarium hobbyists

Two Banded Coral Shrimps in a Vase Sponge

Good afternoon from Curacao! I’m busy in the deep-water lab today cleaning out my old photo aquariums and running around town buying some new ones. The aquariums themselves are in good working order and can be used for other things I just can’t use them to do photos in any more because of fine scratches on the front. When you combine a 105 macro lens with a Nikon D-800 and shoot at F-40 through the glass you pick up every little detail including fine scratches that look like they are on the fish but they are from the glass. That’s why it’s just easier to replace them regularly so you don’t have to spend hours working in Photoshop removing unwanted lines. My two Banded Coral Shrimps, Stenopus hispidus are still hanging out in the same vase sponge for months now, I stop and say hi to them every time I swim by

Want Healthy, Spawning Fish? Feed Them Properly!

Feed your fish. They are hungry. That may sound obvious, but most fish in captivity are starving to death because we are so fixated on water parameters. It’s fine to worry about water parameters, but you still need to feed your fish. Yes, water parameters are important and it’s fine to worry about them, but if you want to keep fish along with your corals, they need to eat correctly. You can deal with the corals later.They’re fish, not iguanas! Most of us are spending so much time trying to keep those colorful corals that we forget about our fish. If your fish are not spawning or looking like they want to spawn, they are hungry or not getting the correct food.

Grooved Brain Coral, Diploria labyrinthiformis

Good morning friends, I’m off to a late start, had to do a quick dive to check a leaking housing that will now have to be sent off for repair. I have a drop dead beautiful colony of Grooved Brain Coral for you all today just sitting all by itself on a sandy plateau with no other corals in sight! These have to be some of the coolest looking corals on the planet, they can be found in the 3-135 foot range and can grow to be about four feet wide, this one here was about three. Grooved Brain coral colonies are known for forming beautiful hemispherical heads just like you see above. They have deep, often narrow, polyp bearing valleys that are separated by broad ridges with wide conspicuous trough-like grooves.

Ikelite, Fluoresence, Blue-Light Diving, UV Dive

Good morning friends! Our friends at Ikelite have just introduced a whole new line of products for all your blue-light diving needs. The photo above shows my Nikon D-300s all set up and ready to go. I have the Yellow Barrier Filter over my 105 macro lens, two Dichroic Excitation Filters over each of my DS-160′s strobes, a VEGA Video/photo light with a Dichroic Excitation Filter (to search with), a pair of Yellow Barrier Filter for the dive mask and my trusty Gamma LED (white light) which I use for an aid in focusing.

Blotched/Borbonius Anthia Care Info

MY FB: https://www.facebook.com/coralfish12g The Borbonius Anthia is most commonly referred to as a blotched Anthia and it is one of the most prized of all reef fish. Because of its unique pink and yellow coloration, the Blotched Anthias has become very popular. Since it is a deep water Anthias, it requires a slightly lower temperate tank. They max out at about 6 inches in full adult form, so they should stay in tanks larger than 90 gallons. Lots of live rock should be in your tank for Blotched Anthias to thrive. The rock will provide lots of cover from lighting and areas to hide if spooked. Blotched Anthias should be fed multiple times per day with a variety of meaty foods such as mysis and brine shrimp. It can be somewhat aggressive so be sure that your tank is ready for it if you are willing drop the $300 dollar price tag that this brilliant fish usually comes with! The video and pics used in this CoralFish12g video are Henry Ludywidjaja's and special thank goes out to him!
