Three weeks ago, I setup this 2.5G aquascape, and if you compare it with my previous update, you can see that some progress has been made. The HC has grown tremendously, largely due to the injection of pressurized CO2. The java fern in the background as stayed largely the same, but that’s about how I want it to be.

Unfortunately, the downoi has all but melted. I suspect that the combination of the buffers in the ADA Aquasoil and the added CO2 has made the water a bit too acidic for its taste. I think the tops have started growing again, so hopefully in a few more weeks it will grow back, obscuring the ugly CO2 reactor on the left side. (Sorry, I don’t remove equipment when taking incremental shots. Note, however, that if you ever enter a contest to do so because some judges view a perfect aquascape, but see a filter intake, and act as if a mortal sin has been committed. End rant.) Comments welcome on what I can do to improve this scape.

I try to feed my fish a varied diet of commercially prepared foods, as well as, live foods when I have the extra time to obtain and care for them. A couple months ago, I was cycling a 10G tank, and when I was feeding blackworms to the rest of my tanks, I inadvertantly threw some in the 10G as well.

Blackworms in the 10G Substrate

As you can see, the worms have taken up residence in the substrate, and have actually multiplied quite readily. This is now the tank that I have my yellow shrimp in, and thus far I don’t think the worms are causing a problem. In fact, they’ve done a pretty good job of cleaning up any extra vegetable matter or algae wafers that the shrimp let be.

It is a little bit disturbing, however, when you look in the tank, and you see a series of worms waving themselves from the substrate, presumably to filter the water overhead. In some ways, I probably should consider this a boon because I am now culturing my own source for blackworms, verses having to depend on my LFS for fresh shipments.

Just hanging around.

Unfortunately, I have not yet been able to figure out how to adequately harvest them from the tank. I have to be awfully quick with tweezers to snag one because when I get close, they speedily retreat down into the substrate. I may be able to siphon the substrate, through a sieve, and get them that way. Any suggestions? Anyone think they’ll be a problem long term?

After much anticipation, today I received a dozen Yellow Shrimp, Neocaridina heteropoda var ‘Yellow,’ via a trade with another aquarist. I’ve seen some pictures of these guys online, and knew that I must have them. Yellow Shrimp are the same species as Cherry Red Shrimp, but they have been selectively bred to exhibit a striking yellow coloration.

As soon as I put them in their own dedicated 10G tank, they went to town exploring the space. I added an algae wafer, which they quickly dismantled, and readily absorbed. The shrimp that I have are not full grown adults. Like cherry reds, when full grown their exoskeleton can become much more opaque in color, making them an incredibly bright yellow.

The best thing about these shrimp is that they’re supposed to be just as easy to breed as the Cherry Reds. This makes sense since they’re the same species, but that isn’t always the case. While some of you may be wondering, “if you crossed a yellow shrimp with a cherry red, would you get an orange shrimp?” The answer, apparently, is no — they would revert back to their drab natural coloration, brown.

It’s a shame that I’ve already stocked my pond with Cherry Red Shrimp, otherwise I would probably have put these guys outside. Last year, I pulled hundreds of Cherry Reds out of the pond in the fall after only having them outside for 3-4 months. I’m hoping to be as lucky with these guys, albeit, inside. If anyone has kept these shrimp themselves, I’d love to hear your experiences.

I’m going to share an embarrassing story about something that I neglected to do, and am continuing to pay the price for. A couple weekends ago, I was at my favorite local fish store, and decided to pickup a dozen Neon Rainbowfish, M. praecox, to add to 7 others I had, in order to form a nice school in my 75G aquarium. The store has a good reputation for properly quarantining their fish for sale, and they all looked extremely healthy and vibrant. So, against my good judgement, I decided to acclimate them directly into my 75G.

Well, the next day, I noticed that 2-3 of the fish were off by themselves, some of them having discolored patches on their bodies. The next day, those fish were dead, and over the next 4-5 days, all 12 of the others continued to follow suit. I contacted the store owner, and he had received similar reports from the other customers who bought the fish, and agreed to fully replace them once he got a healthy batch in. That’s fine, and had I quarantined them, that would be the end of a very sad incident.

Instead, I’ve lost one of my other M. praecox in the 75G, all five of my beloved Red Lizard Catfish, and my newly bought and favored Apistogramma hongsloi sp. ‘Super Rostrich.’ The corydoras, L729 plecos, and Nannochromis nudiceps so far seem to be unaffected, but I’m not considering myself out of the water yet. In addition, I’ve also incurred the extra expense of having to medicate the entire 75G tank, instead of just a 10G quarantine tank.

So, please, learn from my mistake, and quarantine your fish. Even if you just keep an empty 10G aquarium lying around, you can fill it with water from your main tank, throw in a sponge filter (preferably a used one), and be setup for 2 weeks prior to introducing the fish to your main aquarium. I usually follow this advice, and wish I did in this instance, as well.

The Aquatic Gardener’s Association’s 2008 Convention will be held in Atlanta, Georgia later this year on November 14-16. Showcasing one of the best speaker lineups ever, I can’t wait to attend this meeting. Takashi Amano will make his third appearance at the convention, while other former speakers such as Jeff Senske, Karen Randall, and Greg Morin (Seachem president) will present.

New speakers include Benito Tan, who will talk about aquatic mosses and Michael Kane, who will discuss tissue culturing for the aquarist. They’ll do a live Iron-Aquascaper competition, and of course have one of the best aquatic plant auctions on Sunday. Don’t miss it!
