More CW species than I thought!

**Rue** · 06-03-2007, 08:23 PM

Well now...someone else on this forum just mentioned a few species of CW fish that I hadn't realized were CW...and 2008 Aquarium Annual just confirmed it! Wish I had known about some of these before! Temp. between 60-70 F.

1. Goldfish
2. Weather Loach
3. White Cloud Mountain Minnow
4. Buenos Aires Tetra
5. Bloodfin Tetra
6. Pygmy Sunfish
7. Paradisefish
8. Corydoras - heh!
9. Dwarf cichlids : Apistogramma, Laeteara dorsigera, Aequidens spp. Austrolebias spp.
10. American flagfish
11. Bluefin killiefish
12. Blind cave tetra
...and some others from from fast-flowing rivers and streams (where water temp. are lower)...

Who knew???

I think with the cories it will depend on species. Some may tolerate it that low, but I don't think most will, or at least not thirve in it, which should always be the goal. Same probably goes with the tetras. My bloodfins are in with my discus at 86 and are doing great.

Also add to that list, pretty much any north american game fish, IE, catfish, bass, walleye, pike, musky (how cool would it be to have a muskey in an aquarium?), crappie, sunfish, minnows, shad, and the like.

you forgot one fish, danios. Ive read many places danios can survive in room temp. houses with no heater

Also, "black moor" goldfish can tolerate temperatures from just above freezing to mid 70s

...all goldfish...maybe with the exception of the highly inbred fancy varieties can withstand very cold waters...

...esp. the comets and koi...

Here's a list of other coldwater species that I have in my favorites folder.

...I disagree with the guppies...

Some platys and mollies can take those temps also.

I wasn't sure if you were talking about the About.com Coldwater list but I saw it did have Guppies as one of the fish. I was kind of shocked by that as well since I always thought Guppies were tropical fish but I checked it out and both of these reputable profiles say guppies prefer to live in a range of 64F - 84F.
