The GWAPA meeting that I hosted has come and gone, and the weather outside has turned downright chilly, so it was time for me to tear down the pond for the year. I brought the Crinum americana indoors, as well, as a number of the other plants that had spent the last few months basking in the open sun. I also managed to net out about 4 dozen cherry shrimp from the bottom of the pond.

In addition to some outside maintenance, I’ve also been working to break down a few of my smaller tanks in hope that I can replace them with a larger “farm tank” to grow out a number of exotic plants that I’ve been acquiring recently. To that end, with the Jewel cichlids off to a new home, my 20H is completely empty. I piled all of the wood/rocks from that tank into my 20L quarantine tank.

This suits me just fine because I had recently put 20 juevenille bristlenosed plecos from the Catfish Convention Auction into this tank. These plecos are adoring the algae-ridden wood that was in the 20H.

In addition to the plecos, that 20L now contains 3 I. werneri that I’ve been unable to fish out to move to my 75G, and a large number of trumpet snails that retreat to the substrate during the day, and emerge each evening.

I’ve also torn down both of my 2.5G tanks that I had used for my first wormstrate/soil experiment. All that’s left is the 20L and two 10Gs, which I’ll need to consolidate at some point. I’m thinking of getting a 50 breeder, or similarly sized tank for my farm tank. Of course, we’ll see what deal comes along.

My wife and I hosted GWAPA’s October meeting at our home. We had around 30 folks show up on a very rainy day in Maryland for a meeting about photographing your planted aquarium. I did my best to give a talk structured after this post, and hopefully the other members came away with a little bit more knowledge than when they arrived about how to get a semi-decent picture of their tank.

We also asked for nominations for the 2009 board of directors. It looks like the board will remain largely the same, with just the recording secretary slot being new. The auction wasn’t as large as some of them have been lately, but a number of relatively new plants to the hobby showed up at this meeting. A new Glossostigma, Lindernia, and Rotala all made an appearance. Hopefully they’ll soon make their rounds to more and more folks.

After the meeting was over, I fished out my Jewel cichlids, and sent them to a good home with another member who already keeps some Jewels. They were wonderfully personable fish, but were too aggressive to keep with much else. In the end, I plan to tear down a couple of my smaller tanks, so I needed to find a home for them. All in all, a great meeting!

As promised, here is a picture of my 75G after some trimming and cleaning up. I didn’t end up changing the aquascape very much, but that will hopefully come before too long. I have changed the fauna in this tank, however. I managed to fish out about 15 Corydoras paleatus, which I sold in the catfish convention auction.

I replaced them with about 60 Threadfin Rainbowfish (Iriatherina werneri) that I had kept in quarantine for the last few weeks. I also intend to fish out the Goo Obo Gudgeons from my 54G tank to turn this into more of an Australian/New Guinea themed tank. My hope is that the Gudgeons will breed without the Corydoras in there to disturb their eggs. We’ll see! Let me know if you have any suggestions for the aquascape.

After the catfish convention auction, I came home and started acclimating the new bristlenose plecos that I got. I putting them in a 20L quarantine tank, and when I turned around I noticed that none of the sunfish or killies that usually swarm the front of the tank were there. Eventually, I spotted a few of the sunnies dug into the Ranalisma rostrata, and a few others swimming awkwardly at the water surface.

Immediately, I knew what had happened; the CO2 tank ran out, and dumped a ton of CO2 into the aquarium all at once. Right away, I pulled out my Python hose, and did a 50% water change. I also borrowed an air pump from another tank, and threw an airstone into the 40G. At that point, all I could do is wait and hope that I wasn’t too late.

I’m happy to report that despite some really dire looking fish, nearly all of the fish survived as of today. I only have one sunfish confirmed dead, and all killies are accounted for. I was lucky.

So, now the question is what can I do to prevent this from happening again? Well, two things come to mind:

1. I could add a pH controller to control the solenoid on my CO2 tank. If the tank suddenly started dumping, the pH controller would shut off the flow of CO2 once the pH dropped below a certain level. Unfortunately, this is not the cheapest solution.

2. I could attach a low-pressure regulator to the regulator I currently have. This would detect the low pressure that causes a CO2 dump, and vent that gas to the room, instead of the aquarium. The downside to this is that I already have a 3-way manifold on my regulator, which is pretty heavy. I’m not confident that the low-pressure regulator could support that weight.

So, I’m not sure what I’m going to do. At this point, I should have at least 6 months to decide before this could happen again. It’s not even a guarantee that it will happen again. That said, I don’t want to take any chances. Does anyone else have any alternative suggestions for what I could do to prevent this from happening in the future?

After an extremely busy couple of days preparing for and attending a family wedding, I managed to carve out some time to attend the All-Aquarium Catfish Convention auction. I was very pleased to be able to catch up with Dr. Devon Graham, who runs and operates Margarita Tours, which is the company I traveled to the Peruvian Amazon with in August 2007. In addition, from everyone I talked to, it sounds like the convention itself was a tremendous success. I’m very proud of GWAPA participating on Friday night with a workshop about planted-tank-friendly catfish, and representing with a beautiful informational display table. That was all made possible by the work of some very dedicated members.

The auction was huge, consisting of 10 lots of items. I brought 15 bags of plants and fish, and I suspect everyone else did similarly because there could be no less than 1000 items there. Plants, catfish, killies, cichlids, tanks, tools, equipment, it was all present. My only buy of the day was a fantastic grab, pulling 20 Bristlenosed Pleco juveniles for only $14. I have no idea what I’m going to do with all of those if they reach adulthood, but I’ll enjoy raising them up, possibly breeding them, and passing them onto other aquarists. I’d love to hear what everyone else in attendance came away with.
