Over at ADA Thailand, they've posted some pictures of the results of their themed aquascaping competition called Beautiful Glosso. All of the aquascapes contain Glossostigma elatinoides, which is an old favorite of Takashi Amano for a carpet-like ground cover. The tanks are also all smaller sized tanks. There are some very interesting nano aquascapes here, worth a look! You can also check out the winning aquascapes for 2007's nano aquascape competition.

I've personally found that Hemianthus callitrichoides (HC) is a slightly better ground cover for smaller tanks, since the leaves are smaller and it requires slightly less maintenance. One thing to note about both ground cover plants is that eventually, they will begin to grow on top of themselves, killing the older growth and uprooting the remaining plants. This causes "bubbles" in the carpet to form. I haven't yet found a way around this other than to rip up the carpet and start over. Luckily, this usually doesn't happen for at least 8-12 months, depending on the growth rate.

This week's aquascape is called Walking Aoyama by Justin Law. It's quite a contrast from last week's aquascape, and is more of an iwagumi style. The most striking thing about this aquascape, for me at least, is the elevation. To get the substrate to stay in hills like that is extremely hard but very very rewarding if managed. It emulates a grassy hillside and is very relaxing to look at. Hemianthus callitrichoides (HC) makes up the majority of the plants in the aquascape, with some moss hiding here and there. This aquascape actually inspired me to make my own iwagumi style layout using HC and rocks, and let me tell you, it isn't easy! For more pictures, visit Justin's Walking Aoyama photo album.






Starting a bit of a new feature with a weekly aquascape chosen by me for it's beauty and inspirational qualities. This week's is a 75 gallon tank designed and created by Luis Navarro. The main design element of the tank is the open sand foreground and the low maintenance plants. There are no stem plants in this tank, but lots of crypts, moss, and anubias. The overall effect is a mesmerizing and truly beautiful aquascape that blends aspects of the Dutch and Nature aquarium styles. For more information on the tank, check out the journal here. Enjoy!






Here they are, the top 10 tanks in this year's ADA Aquatic Plants Layout Contest. Click on the images for a larger version. I must say, there are some absolutely stunning aquascapes in this bunch. Several are quite unique too, including position 1 and a really really long aquascape in position 7. I'll be posting some more tanks later. Enjoy!

Here is a contribution from one of my readers (Preeti Shah) about her pet terrapin here. It is very nice red ear slider.

Some comments from Preeti Shah: well i have it since Feb18′ 2008.. It was ma mom’s birthday and i got it as a gift from one of ma close friend .. He found her in one of the pond here in Mumbai.. it was a cute ltl baby and hav been ma first Pet ever.. A beautiful Gift i recieved.. and will Treasure it till Eternity.. Taken by Surprise i still dont know if its “HE” or “SHE” ;))

Thanks for your kind contribution, Preeti!

Pictures of this year's ADA Aquascaping Contest 1st place aquascape have been posted on CAU along with an interview of the winning aquascaper, Mr. Cheng Siu Wai. The aquascape is called "Danxia" and is quite unique. Check out the interview as well. Although the English translation is a little rough, it's still worth the read!

Expect the rest of the top 10 aquascapes to surface soon.

Description:

The blue lobster that is found in aquarium hobby is actually not a true lobster, but rather a blue color crayfish. For the purpose of this article, I will refer to them as blue lobster. Like its name suggest, the Blue lobster is blue in color and shades of blue vary from bright electric blue to a duller bluish white. Other then their unique coloration, they are highly similar to other crayfish and lobsters. By maturity, Blue Florida Crayfish achieve lengths of 15 centimeters.

Habitat/Care:

In the wild, Blue Lobsters are usually found in wetlands biome or habitats that have distinct wet and dry seasons. Although Blue Lobsters trend to be abundant in wet seasons, they are extremely well hidden in periods by burrowing into the mud. When water is abundant, Blue Lobsters stay near the bottom of the flooded area, eating invertebrates and algae.

It is recommended that the tank mirror their environment by providing some fine sand or gravel, and allow a cave or place for hiding when the blue lobsters are stressed. Plants are highly recommended as they provide a source of food and hiding places. As long as the tank contains enough water, blue lobsters should be bury themselves.

Because they require a large tank, blue lobsters should be keep in a tank of at least 20 gallons. They are excellent escape artists, and the tank should have a tight lib.. Temperatures should remain between 10 and 22 degrees Celsius. They usually require pH values upward of 7.0. It has been reported that the addition of freshwater salt greatly enhances the health of this species.

Usually, Blue Lobster get along well with other fast, medium size fishes. However, small and slower fishes will be eaten, and larger but slower fishes may be injured by the Blue Lobster. Larger, carnivorous fishes view Blue Lobsters as a tasty snack. Blue Lobsters are highly territorial and they should NOT be kept with others of their kind, or they may fight and gravely injure one another, unless there are lots of hiding place and the tank is large enough for all of them.

Blue Lobsters continuously molds (they will drop off their shell) as they grows bigger. During the juvenile period, the molding is fairly rapid, but slows down as it grows

Diet:

Blue lobsters aren’t actually very fussy when it comes to food. In the wild, they eat aquatic plants, algae, rotting vegetation that falls into the water, snails, fish, and even the decomposing flesh of animals that die in or near the water.

The trick is never to over-feed them, as uneaten food could contaminate the tank quickly. Fish flakes are great for baby lobbies, while shrimp pellets are perfect for adults.

Two large crushed flakes a day are plenty for babies, one in the morning and another in the evening. For adults, a large pellet for breakfast and then another for dinner should do it. You can also try feeding them water lettuce, water hyacinth, water cress and romaine lettuce.

Breeding:

The male blue lobster’s claws are generally larger and more elongated and if you turn him upside down he has two claspers near his vent that look like hockey sticks. The females blue lobster claws are shorter and more rounded and she lacks the claspers. During the mating act, the male initiates copulation, and the Blue Lobsters will clean each other as part of the mating ritual.

After mating, the eggs are carried in the female pleopods. Blue Lobsters eggs normally hatch in about four weeks. They emerge as miniature versions of adults, though lacking reproductive organs. In the first 24 hours of life, Blue Florida Crayfish fry must molt, and many may not survive this first molt. You should begin changing the water regularly and maintaining the best water conditions possible to aid the fry in surviving. They can be fed freshly hatched brine shrimp, microworms, or liquefied foods. After about two weeks, the young Florida Blue Crayfish have generally become much more hardy. They will still be rather transparent, but by the time they reach sexual maturity they will have gained adult coloration.

Excellent Selection of Accessories

At the basement of Plaza Singapura near Dhoby Ghaut MRT, there is a new fish shop nested near the escalator at basement 2. This fish shop sells a wide range of both marine and freshwater fishes. Below are some pictures taken from the shop. Due to strong lighting, some of the pictures are not as clear.


Koi Pond

Gold Fish

Of interest is the koi pond where there are lots of baby koi and excellent goldfish display as well some varieties of marine fishes.


I love the gouramis swimming in the tank. Kinda take my breath away.

Warning: The prices of the fish here tends to be higher than most places, but it is conveniently located in one of the better shopping mall in Singapore where rental is expensive.

I've covered two other major schools of aquascaping for planted tanks before, but both of those are relatively high-tech, and high maintenance. For those of you who either don't have the time, patience, or just the wallet for a high-tech Dutch or Nature style tank, or for those of you who have been burned out by one, there is a third school.

This third school, often referred to as "el Natural," and sometimes Natural Planted Tanks (NPTs), is based on a low maintenance, low-tech approach pioneered by Diana Walstad. Outlined in her book, Ecology of the Planted Aquarium: A Practical Manual and Scientific Treatise for the Home Aquarist, the approach has several basic tenets:

  • Regular potting soil, capped by small gravel is used as substrate
  • No filtration is needed, aside from a powerhead for water movement
  • Lighting is low, 1-2 watts per gallon, and is often supplemented by sunlight from a window
  • No fertilization or CO2 is used, only liberal fish feeding
  • Water changes are done only ever 6 months or so
  • Plants will act as filters and fish will act as fertilizers, creating a balanced ecosystem
The end result is a tank that looks very different from any Dutch or Nature style aquarium, but that requires almost no maintenance, while maintaining a lush planted look. The types of plants available to someone starting an "el Natural" fish tank are somewhat limited, since lots of plants require high light and fertilization, but algae is rarely a problem. Unlike Dutch and Nature style aquariums, there is no set school for plant placement or composition of hardscape. This approach is also not designed for someone who likes to rescape their tank every few months, as moving plants around is difficult to do without disturbing the potting soil underneath the gravel. The natural soil substrate is probably the most volatile part of an "el Natural" style fish tank, and there are lots of do's and don'ts explained in Diana's book. However, once you get it set up, an "el Natural" style tank can be perfect for someone who is tired of dosing, testing, and re-dosing every day or for someone who just doesn't have the time for a high-tech aquarium.
