Bursa Triggerfish (Rhinecanthus verrucosus)

The Bursa Triggerfish or Rhinecanthus verrucosus is one of the many different species of Triggerfish on planet earth. This particular species can grow to about 9" in length and originates from Indonesia. They are called several different names throughout the world including the Black Patch Triggerfish and the Blackbelly Triggerfish.

The Bursa Triggerfish has a mustache of sorts that really gives them an unusual appearance. They also have a colorful mask around their eyes and the classic Triggerfish beak-like mouth, not to mention their dorsal spines that give the Triggerfish its name. This fish will use these spines to wedge itself into tight crevices when threatened.  Bursa Triggerfish can also be identified by a large black circle that is found on the lower half of its body towards it caudal fin (tail).
As you can imagine these saltwater fish are very popular in an aquarium setting and are fairly reasonably priced which makes them all the more popular. An aquarium of about 80 gallons or more with the following water conditions will work well, 72-78° F, dKH 8-12, pH 8.1-8.4 and sg 1.020-1.025. These fish are carnivores that should be fed meaty foods like small fish, squid, krill, clams, and plenty of hard shelled shrimp to help wear down their ever growing teeth. One interesting fact about these fish is that they tend to make a grunting sound and will often rearrange the furniture in the aquarium.

Bronze Whaler (Carcharhinus brachyurus)

The Bronze Whaler or Carcharhinus brachyurus is a species of shark that is a commonly found near the coast in all the subtropical oceans and seas in the world, with the exception of the east cost of North America.

Brozne Whaler Sharks go by a couple different names throughout the world including the Narrowtooth Shark, and the Copper Shark. These saltwater fish have a broad snout and are lacking a interdorsal ridge. The Bronze Whaler is actually a grayish bronze in coloration with white on their lower bodies.

Guadalupe Bass (Micropterus treculii)


The Guadalupe Bass or Micropterus treculii is a freshwater fish that is often found in flowing waters almost exclusively in the state of Texas where it is the official state fish.  Also known as the Black Bass, this fish is green in color and can be differentiated from its close relative the Smallmouth Bass by the lack of vertical bars across its body.  You can tell the difference between this fish and the Largemouth Bass by its jaw.  The jaw of the Guadalupe Bass doesn't extend beyond the eyes like the Largemouth Bass.  It can be particularly tricky to tell the difference between the Spotted Bass.  Just watch the coloration, the Guadalupe Bass's colors extend much lower on their bodies than the color of the Spotted Bass.

This species of Bass does not grow very large because of their habitat.  Often caught in small streams these fish can only grow to about 4lbs.  They reproduce rather quickly though, becoming sexually mature at just one year old.  Guadalupe Bass will spawn in the months of March through June.  Building a gravel nest, they will lay up to 9,000 eggs in shallow waters. The males will keep guard of the nest until the eggs hatch.  You can see the Guadalupe Bass underwater in the video below...
