I have a 220 liter tank, 100cm x 40cm x 70cm (er I think that's 40" long and 15" front to back). It's got lots of plants and three pieces of bogwood. I have had a bristlenose in there since about March and I've loved watching him grow. He does grow fast, I think he's about 3.5" long now (and I do ...

have you seen white cloud mountain minnows? they're rather nice and would do well in your tank.
I have seen white cloud mountain minnows and I agree; they look great! I think they will be the first fish I put in unheated tank #2. And peppered cories will be the second ones, after the tank is ...

Why I don't just go out and buy a heater: I simply like the idea of keeping the tank as low-tech as possible. I find it more interesting to find plants and fish that work well in the simple setup I have rather than trying to make my setup more complicated to accomodate other fish. I would change my ...

I have Otocinclus cats in both my tanks, and they do help quite a bit with algae on glass, plants, rocks, and other surfaces.

Is this an unheated tank? I'd be very interested to know if one can keep otos without a heater, as all I had read suggested a minumum temp of 22 or 23C ...

Just in case anyone cares, here's what I ended up with: 2 hillstream loaches. They are not catfish at all! They bear some resemblance to very small (2") stingrays. They have sucker bellies that they use to keep themselves attached to rocks as they feed on algae in very swift running streams. They ...

I have a 24" (20 Am. Gal, 75l) planted tank that I set up towards the end of September. It is unheated. I would like to keep it that way, as heaters do nasty things to fish when they go wrong. The tank temp ranges between 20-21C (68-70F).

It currently has 4 zebra danios and 2 rosy barbs, a male ...
