Xenia Refugium. What’s in/by your sump?

A twist on the refugium concept. The Xenia refugium.

A twist on the refugium concept. The Xenia refugium.

 Inspired by Jake Adams and Julian Sprung’s friendly debate on Refugiums last MACNA, I decided to remove algae from my Refugium and replace it with Xenia. I wanted to remove any nuisance algae as well as Chaetomorpha and Caulerpa, so I added urchins, snails, and tangs. I also decided to try 24-hour lighting for the benefit of a more stable pH. I wasn’t sure how the Xenia would respond, and I was ready to switch to a reverse day/night cycle if needed.… More:

How to Prevent Fish from Stealing Coral Food

Brain coral with feeding tentacles out at nightWhen it comes to acquiring food, fish will take the path of least resistance. And one of the best ways for a fish to score an easy meal is to snatch morsels away from their glacially slow-moving invertebrate tankmates. Heck, it’s practically like taking candy from a baby, except babies usually cry a lot louder when they’re robbed of treats. For hobbyists who keep corals or other invertebrates with a high demand for regular targeted feeding—e.g., many LPS corals and anemones—such food thievery can be a genuinely aggravating issue. The good news is, using one or more of the following techniques, it’s often possible to eliminate, or at least reduce, this bad behavior:Distract the culprits You may be able to buy your coral a few precious moments at mealtimes by first delivering food to the fish in another part of the tank and then quickly target feeding the coral. Of course, this is only effective if the fish haven’t already learned to identify the coral in question as a source of easy victuals. In that case, they’ll likely just gobble up their own food and then proceed to shake down the coral anyway

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.

Aiptasia-X Kill Compilation

http://www.redseafish.com/reef-care-program/aiptasia-x/ In this CoralFish12g video I will review, and demonstrate Aiptasia-X by Red Sea. Within minutes of ingesting the Aiptasia-X the anemone will implode, eradicating both the anemone and planulas. This is the ultimate solution for getting rid of these pesky pests.

Pillar Corals, Dendrogyra cylindrus, Stony corals

Good morning from wet Curacao! Yes, we are finally getting rain and it is great! I have a beautiful little colony of Pillar Corals, Dendrogyra cylindrus for you all today that I found last year at my favorite dive site on the island, Whatamulla which is located near the western tip of the island and is only accessible by boat. These spectacular “pillar-like” stony corals grown straight up and can reach a length of about 10 feet, that’s a tall coral! I normally see these in the 35-50 foot range but they can be found as deep as 65 foot and as shallow as 4, that’s quite a difference in depth. Pillar coral (Dendrogyra cylindricus) is a hard coral or stony coral (order Scleractinia) found in the western Atlantic Ocean and the Caribbean Sea

Study Shows Corals Consume Microplastics

Unfortunately, the solid plastic trash we often see in the ocean (bottles, bags, etc.) is only a portion of the plastic waste that has been deposited there. A considerable amount of waste may be present in the form of microplastic. Microplastics are basically miniscule bits of plastic that can be suspended in the water column. Though the environmental effects of microplastic pollution are not yet well understood, the consensus among marine biologists is that they pose a global threat to marine ecosystems. Researchers from the ARC Centre of Excellence for Coral Reef Studies at James Cook University set out to see if corals (which are non-selective filter feeders) ingested microplastics. Corals from a clean area were placed in a contaminated area. After two nights, they were analyzed for the concentrations of plastics. Results indicated that the corals consumed plastic at a rate only a little lower than that of their natural planktonic food. Plastic materials were found engulfed in digestive tissue, suggesting that it may hinder a coral’s ability to digest its food. The team is now investigating what… More:
