Updates...

2 and a half months since the last entry... You would think that I've a lot to fill in.... Well yea! Lots have changed!! Revamped to a 4'x2'x1.5' tank for my plecos, and 4'x2'x2' for my "monster" fish! Wee.. Although now I hardly have time even to look at them carefully, they are my babies and always nice to come home and switch on the lights to see them swimming around.

What's in that monster tank?
1 x 10" THRTG
1 x 6" Sakura Ray
1 x 9" Ornate Bichir
1 x 6" polo
1 x 6" Red Tail Gourami
1 x 4" Indonesian Tiger
1 x 3" Indonesian Tiger

What else?
Lost almost all my goldline cories. They cost a fortune and I'm never getting them again!!!

Jaguar Catfish Liosomadoras oncinus


Scientific Name : Liosomadoras oncinus

Family : Doradidae

Common Name : Jaguar Catfish

Maximum Size : 18cm / 7"

Origin : Rio Branco, Brazil - white water river

Temperature : 20-24pH Level: 5.8-6.5


Things to note : The Jaguar catfish (Liosomadoras oncinus) is named after the intangible Jaguar (Panthera onca), and just like its feline namesake, the Jaguar catfish can only be found on the South American continent. It has jaguar skin patterns and is very attractive.


Personal comments : They are quite territorial and yet fragile. Be sure to have a stable tank environment. I've lost my two specimens quite quickly.


Tips : Try to keep a pair, male and female. And have a lot of patience; they do not move at all when there is light, and they are very sensitive to light!


......................................................................................

Sexual dimporphism / reproduction : Determine the sex of a Jaguar catfish is easy, but reproduction has not yet occurred in captivity. The female fish is shorter than the male and has a heavier belly. You can see the male's reproductive organ at the anterior edge of his anal fin.


Feeding: In addition to the leftover food it will scavenge from the bottom, the Jaquar Catfish should also be fed sinking carnivore flakes, pellets, tubifex, and bloodworms.


Behaviour in captivity: Unlike many other popular catfish species, the Jaguar catfish does not form schools. It is a highly territorial species and this must be taken into consideration when you set up your aquarium. It is possible to house several Jaguar catfishes in the same aquarium if it is large enough, but this calls for a clever aquarium decoration that brake up the aquarium into several different territories. There must also be plenty of hiding spots throughout the aquarium. Include driftwood and pieces of PVC pipes or similar. If you hear strange sounds from the aquarium at night, it is Jaguar catfishes trying to stake out their territories. Rivaling the Jaguar catfishes will rotate the spines of their pectoral fins at the base; thereby producing a sound somewhat similar to a foghorn or tuba.


As nocturnal predators, these catfishes should only be maintained with community fishes of equal or greater size. As one of the most beautiful of all South American catfishes, the Jaguar catfish can be recognised by its striking yellow blotches and dark lines on a brown and white body.

Pseudas - Filamented Beauties?

Just wondering this aloud: Do most pseudacanthicus species have lyretails/filaments? It's interesting because if that is the case, it will be a added bonus to pseuda lovers everywhere. Wouldn't it? Already they rank among the most beautiful plecos in terms of their streamlined body shape, beautiful colours, and a kick ass attitude. Add a lyretail in, and they must be heaven-sent! :)

I ask this because I do have a few specimens from different species, which have that long lyretail already there, or growing fast. I'm extremely attracted to lyretails admittedly, because they give the pleco an added dimension, like a ballet dancer holding streamers - poetry in motion! I did consider keeping plecos that are famed for their long filaments, such as L90, Adonis and L273, of which I now have the latter two. Having found that there was a shipment of L25s that came in 2006 with long filaments, I went out in search for them and found 4 to my liking. In addition, I now have a L24, L273 and L114 that have lyretails, or are developing one.

One fact I found about such specimens, is that perhaps due to the better genetics, when their lyretails break off, these often grows back, and at a faster rate than normal. Recently I have had 2 L25s and an Albino Adonis breaking their tails, and within a month, they've recovered almost 1-2 inches of tail!
