Triggerfish Parental Care

Triggers are rough-and-tumble reef dwellers that often create problems in a community aquarium, but those from the genus Xanthichthys are comparably peaceful and can sometimes even be housed in a reef tank. Learn all about those “Marvelous Triggers” in Edward Adam Jackson’s article in the September 2011 issue of TFH http://www.tfhdigital.com/tfh/201109/#pg99.

Leopard Wrasse in the Aquarium

Leopard wrasses make beautiful additions to the marine aquarium provided their exacting needs are met. They must be kept in a large, established reef with plenty of hiding places, room to swim, and a secure cover to prevent them from jumping out of the aquarium when startled. Another important consideration is to purchase a healthy looking wrasse from the start.

Take a look at this Leopard Wrasse in an Aquarium and be sure to get all the information about leopard wrasses from Bob Fenner’s article in the August 2011 issue of TFH http://www.tfhmagazine.com/details/articles/leopards-for-the-reef-full-article.htm.

Spawning Bundoon Blennies

Clownfish are among the most popular fish that beginning marine fish breeders attempt to reproduce, however they may not be the easiest. Although their larvae are larger than most, and therefore easier to raise, it can take years for a clownfish pair to begin spawning.

That’s why master marine fish breeder Matt Wittenrich, PhD recommends using bundoon blennies Meiacanthus bundoon for a beginner’s first project. Bundoon blennies have large larvae that are relatively easy to raise and can even handle less-than-perfect water quality.

Check out the mating dance in Matt’s video of his Spawning Bundoon Blennies.

Amphilophus hogaboomorum “Rio Cholteca”

Mo Devlin, chairman of the American Cichlid Association Convention and superb photographer, wrote about how he captures the his fish’s most amazing moments on film. Check out his full article “Cichlid Camera Magic” from the July 2011 issue of TFH at http://www.tfhmagazine.com/details/articles/cichlid-camera-magic-full-article.htm.

But Mo doesn’t limit himself to photos only, he also makes incredible videos of his cichlids. In particular, he created a video of the Amphilophus hogaboomorum featured in the article. The video shows fish that Mo collected in the Rio Cholteca near Teguchagalpa, Honduras. The tank includes one female (the smallest one) and several males in a 180-gallon tank.

Restoring Vision to Blind Cave Fish

By Richard Borowsky

If you want to see the full effects of inter-cave hybridization on eye size, you have to look at very young fish. The eye rudiments of Tinaja and Molino cave fish are much smaller than those of surface fish. Not only are they smaller, they are completely non-functional. In contrast, the eye rudiments of the Tinaja x Molino hybrids are significantly larger than those of their parents. Myquestion was, “Are they large enough and well enough formed to work?”

In order to determine whether any of these fry could see, we placed them individually in a shallow dish in a syrup like substance that made it difficult for them to swim, but did not interfere with their breathing or their eye movements. The dish was surrounded by a vertical cylinder with black and white vertical stripes that we could rotate. When we tested the surface fish, its eyes followed the stripes as they rotated and then, going as far as they could, they would snap back. They would then follow again and snap back once more. This happened repeatedly, until we stopped the movement or reversed the direction of rotation. When we reversed the direction, they would follow in the new direction and snap back in the opposite. The surface fry did this because they could see and because following stripes is an instinct. When we repeated the experiment with either Tinaja or Molino fry, neither of them showed any eye movement at all. The same is true when we used fry from other caves, such as Pachón. Of course, they failed to exhibit the response because they were blind and could not see the stripes.

To find out what happened with hybrid fry, with parents from different caves, and to see a video of these experiments check out http://www.youtube.com/watch?v=5GU9hKN_yYQ.

12ft. Monster Move – Aquarium Design Group

Another lighthearted oriented movie, this features the giant gourami piglet who is owned by a caring hobbyist who considers her fish part of the family. This shows the whole process of breaking down the existing aquarium and replacing it with a new 12 foot aquarium for this 2-3 foot Giant Gourami and his compatriots!

Aquarium Design – Tanglerose

The Tanglerose hardscape design is focused on a new approach to driftwood placement and has a distinctly foreign feel due to the type of material and fish selected for use. The music selection compliments this to give the presentation a distinctly “indian” feel to it. There is a distinct impression of being in a foreign world that is both very different from our own culture and similar enough to be impactful.
