New Sub-Species of Cory Cat
6 Attachment(s)
I have started my first planted tank, 90 gal, and it has been up and running for a little over 2 months. I choose a heavily planted cycling method.
The fish population so far has consisted of my clean up crew followed by ten Rummey Nose tetras. All are doing fine.
In the beginning I placed 5 Bronze Cory Cats, and a week later 5 Skunk Cories. One of the Bronze is a real wave rider, spending a lot of time in the outflow current. And then he/she went missing and I presumed a casualty.
Two days ago I was doing a water change and noted that the pre-filter pad in my sump (I have a trickle filter in a 20 gal. sump) appeared to be draining poorly probably clogged with sediment. So I took off the sump top only to find a Cory swimming around in a 1/4 inch of water on the 12x12 filter pad, bathed by the overflow water from the tank. He/she had been in the top of the trickle filter for at least three weeks in total darkness.
Back in the tank I had a new very pale silver, apparently air breathing, Cory. (I know they are "gut breathers", but this was taking it to a new level.) Corydorus lazarus. BTW, I have no idea how he got into the sump top, given my filter configuration.
The C. lazarus is back to wave riding, has put on a little weight, and is bronzing up nicely in all that light.
I do a lot of nature photography, but good aquarium shots are harder than I thought. Need a lot of work.

Hah! Glad your cory turned up and seems to be okay, they can be pretty amusing critters.

Beautiful tank and pics, btw.

out of curiosity, what's the substrate you are using?

Eco Complete. With that macro it might appear to be a little harsh for Cories. They don't seem to mind digging in it and show no damage to their "whiskers".

That is such a neat looking tank!

Nice setup and pics!

New territory for me, always had reef tanks.
Starting to get some plant growth. From my limited experience, I would recommend the heavy planting to cycle a FW tank. I used Eco Complete and dose with Excel every other day. So far very little brown algae (four Gieseman T5 48" 54 watt bulbs, 2 daylight and 2 aguaflora on timers) and to date 0ppm Nitrites and Ammonia. So far just a trace of Nitrates, this past water change.
At some point I would like to add adult Discus.
We shall see...

Beautiful tank and great pics! I love the tannins.

SMB 11-20-2012 06:17 PM

I soaked that wood for a month. I like the tannins as well. The tank will clear up some with a water change, but by the end of the week it is pretty brown. The Rummy Nose red really pops. They are tough to photograph!

Corys can be amazingly resiliant.

Last spring I had a 20g backwall blow out and spent the wee hours of the night rescuing fish/plants and getting them transferred into temp holding. Polished gravel substrate heavily planted quickly turns into a couple inches of pure mud. Pulled as many corys and ottos out as I could find, often burying them in gravel piles as I tried to corral 'em. Finally called it a night, leaving the "empty" tank with 2-4" piles of gravel and maybe 1/4" standing water between the piles.

The next morning I started shovelling the gravel out onto a screen to finish rinsing it--and turned up a cory! Plopped her immediately into my emergency tank and after a few hours sulk in the weeds she was back to swimming with the herd.
