Today was the final day of the 2006 Catfish Convention, and consisted solely of an all-day auction. This auction was made up of 10 lots, plus a dry-goods lot run by Ray “Kingfish” Lucas to help raise money for next year’s convention. The auction started at 10:00am. By 1:00, there were so many items to auction, that they had only gotten through lots 1 and 2, and the dry goods. I didn’t stay until the end because I had blackworms that I needed to get home to the refrigerator, but I imagine it went on for hours after I left.

(Everyone checked out the auction goods before it started.) 

I came home with a fair amount of “loot” from this convention. I don’t have any pictures of it now, but I’m sure I’ll post some in the future:

I came home with a fair amount of “loot” from this convention. I don’t have any pictures of it now, but I’m sure I’ll post some in the future:

• anubias barterii nana “petite”
• 3 Red Lizard Whiptail Catfish
• crypt. wentii. (thanks Sean)
• 2 pairs of Dwarf Crayfish, regular brown variety.
• 5 juenvenille L-279 Bristlenosed Plecos (Ancistrus sp.”Huacamayo”)
• 13 young melanotaenia praecox rainbowfish.
• 1 Pair apistogramma viejitas (This is my favorite pull for the weekend!)
• 1 potion of Blackworms from Eastern Aquatics.

Today was the second day of the 2006 Catfish Convention. I was able to attend most of the sessions today, and I must say that all were of very high quality. Tomorrow, the convention will wrap up with an all-day auction.

The first session of the day was about African catfish, and was presented by Mark Soberman. Mark gave a brief overview of the 9 families of catfish native to the contient. A few highlights included Austraglanidae, who are an endangered species in South Africa. Of course, he had to mention the Claridae family of catfishes, who are an air-breathing group of catfishes that are now banned in the U.S. after a series of incidents related to Snakeheads. Don’t forget the Malapteruidae, who include a few electric catfish, and the Mochakiadae, who are Africa’s largest family of catfish.

Really, all of these were just leading up to Mark’s favorite group of African catfish, the Synodontus. Synodontis catfsh include many of the fish we are familar with in our LFS’s, such as the upside-down catfish. He describe a number of fishes, but also lamented a little bit, at the current influx of Synodontis hybrid fishes coming out of Singapore fisheries. Mark feels that African catfish species are unique enough in their own right, that the hybridization only confuses hobbiests.

Inbetween sessions, I decided to take a trip down the hall to the Fish Showroom. This room have about 200 tanks in it, stocked full of conference attendee’s best fish from their fishrooms. There were more than just catfish represented in this rooms; there were: catfish, killies, bettas, cichlids, livebearers, danios, pretty much any class of fish you can think of.

After purusing the fish, and admiring more than a handful of beautiful specimens, I headed back to the lecture hall for Ian Fuller’s second talk of the conference about Breeding Corydoras.

Ian covered all aspects of his breeding techniques for Corys. He recommends the following:

– buy fish already at breeding age.

– know how to seperate males from females. For example, males often have an elongated ventral fin. Females usually have broader bodies. Males are usually the more colorful fish.

– Use smaller tanks, such as 10-20 gallons.

– Use RO water, adjusting it to 6.5-7.0 PH, GH 0-3 degrees, mix in 1 part Epson salt, 1 part Marine Salt, and 2 parts chalk.

– Use fine grained salt/gravel. Do NOT use a bare-bottom tank because it’s bad for the Cory’s barbles.

– Setup the tanks with oak leaves, beech twigs, java fern/moss, etc.

– Feed a variety of foods. Brine shrimp, microworms, earth worms, and Tetra tabs are especially good.

– Trigger spawning by doing massive water changes, temperature changes, PH crashes, etc.

– When you see eggs, add Alder cones to the water as a mild anti-fungal treatment. Move the eggs to a hatching container with Java moss.

The last session I attended today was by Dr. Peter Unmack about Austrailian catfishes. I think that Dr. Unmack might have had the most interesting talk of the day, largely because it featured catfish that I had never seen before.

There are only two families of catfish in Austrailia. Many of the species in these families actually spend a portion of their life in saltwater. Many are mouthbrooders (pictured right). Unfortunately, there aren’t many Austrailian catfish that are suitable for aquaria. Furthermore, the ones that are, rarely are seen because their natural habitats are too remote to easily collect and ship. This is a shame because most of these catfish would be relatively easy to keep. For example, they can tolerate a wide range of PH swings because in nature, when streams flood, the solids are diluted, causing the PH to drop. But, when the water recedes, the PH skyrockets. The catfish don’t care. Infact, this fluxation might trigger spawning.

The Plutosidae family is a really interesting family of catfishes. The look like someone took a South American catfish’s head, and put it on the body of a knifefish, or eel.

One of the most widely distributed fishes from this family is the Neosilurus hyrtlii (left). As you can see, they don’t have distinct caudral or dorsal fins. Peter also described the Neosiluroides cooperensis, which he thinks is one of the most bizarre catfish in Austrailia. This fish is found in Cooper Creek, has unusually good eyesight, and is an adept predator of other fish and shrimp. They lay huge eggs, and are rarely caught under 6″ in size. In his experience, it will kill anything it see’s.

Peter wrapped up his talk with a slideshow of other Austrailian fish, including rainbowfish and gobies.

After this session, I decided that I couldn’t risk not buying a few fish/crayfish that were on sale out of one of the hotel rooms, so I promptly bought more than I needed, and headed home to put my new fish in their tanks.

Melanotaenia splendida australis is a beautiful, but fairly common, rainbowfish. I think this was the cheapest rainbowfish that I have in my 54G, rainbowfish, tank. I believe I paid $1.99 for the juenvenille, drab-looking, fish. Despite it’s youthful appearance, as an adult, I think it might be the most prolific fish, both in spirit and color, that I own. I’d recommend to anyone who wants to try rainbowfish.

I was fortunate to catch it displaying to another male rainbowfish in the tank (below). These fish truly are a marvel to watch, especially in the morning, when they’re especially spirited.

Today was the first day of the All Aquarium 2006 Catfish Convention put on by the Potomac Valley Aquarium Society, a large local aquarium club. The program director is Andrew Blumhagen (left), who opened the convention by introducing to us hobbiest, and corydora expert, Ian Fuller (right), all the way from Great Britain.

Ian’s first, of two, presentations at this convention was largely about identifying corydoradine catfish. He presented a number of well drawn slides, such as the one below, showing in detail the growing number of problems in the

classification system of these fish. Basically, he demonstrated how two entirely different species can look too similar to differentiate when put side-by-side. His claim, is that you must know the exact locality to correctly identify the fish. Toward the end of his talk, he mentioned that the situation is only being exacerbated by human factors, such as deforestation, pollution, and dam construction. These factors are causing species to migrate out of their normal habitat, entering new environment. The changes in their environment are causing the fish to develop different color morphs, further complicating identification.

The second speaker at the convention was Lee Finley, who gave a presentation focusing solely on how to feed your catfish the kind of food they would normally eat in the wild. Basically, catfish don’t just eat algae and detritus when in the wild. Depending on the species, they’ll eat wood, bark, algae, detritus, veggie matter, fish, insects, larvae, worms, the list goes on. His slide of the commonly known Vampire Pleco, or Rabbit Tooth Pleco, illustrated how specialized some of these catfish have become. These Plecos used their “two front teeth” to chisel away at wood, searching for inserts; much like a wood pecker would do in a forest. Unfortunately, Lee had to rush through his talk in order for everyone to make it to the much anticipated Italian dinner.

Finally, the last topic I was able to hear for the day was put on by Dinyar and Rusty Lalkaka. This father and son duo gave us a quick tour a number of interesting Asian catfishes. Even though Asian Catfish are only second to South American fish in terms of the diversification of both species and genus, few hobbiest know or keep them. One of the lone exceptions is probably the glass catfish, which are at every LFS in the world.
The last two topics were titled “Catfishes in the Classroom” and “Breeding Loricariids.” Unfortunately, I wasn’t able to stick around for those two, but I’m sure they were quite interesting. Stay tuned for more convention coverage from Day 2, tomorrow!

A few weekends ago, I emptied everything out of this tank, except for the SeaChem Oynx sand substrate. Previously, I also had a “wall of wood” with anubias and java fern plants attached to them. Unfortunately, I had that scape in place for about 2 years, and most of the plants had overgrown themselves into places that were no longer aesthetically pleasing. So, I basically wanted to keep a similar scape, with just a few adjustments that would open up more free space for the rainbowfish, who had grown quite large since I introduced them to the tank.

(54G Tank – 10/18/2006)

The foreground itself is quite bare right now. I have a few varieties of crypts planted there that, in time, should fill out the foreground quite nicely. I want to remind you that this is the tank that I don’t do anything to except for bi-weekly water changes. I have phyllanthus fluitans floating on the surface to soak up any extra nitrates. I rarely dose the tank, and I don’t supplement any CO2. I have a JBJ Formosa fixture on top that sports 2x65W PC lights and some NOISY fans. All in all, so long as the powerhead and filter keep a fairly high amount of circulation going in this tank, I have zero problems. I’d welcome any low-light recommendations for the foreground.
