Alright, so I have 3 Julii Cories which I have rescued from different sources (one was givin to me by a friend who couldnt understand why his cichlid ate all of its fins off, one was returned to our store because it has a "crooked" back (which it doesnt) and one was givin to the store where I work when they couldnt keep the bowl it was in clean... arg)

Anywho, I had a tropical tank a while ago, but had to tear it down for a mulitude of reasons, and the cories, being the only ones left, got moved into my blind goldfish tank (has a moore, a celestial and a bubble eye) During the summer, the tank was around 76, which the goldies loved ("extra" fancy goldies I have found like warmer water then say orandas or commons) and the cories seemed to not mind... and so far winter has been mild here... but lately its turned cold, and now my tanks down to 68. will this harm my Julii's? they are eating and playing fine from what I can see, but Im no catfish expert, I took these poor guys out of pity, not knowledge, which is backwards, i know.

any help will be appreciated.

Well, your 68oF is about my 20oC. From what I understand, some Cory's withstand down to 10oC in the wild, depending on their natural distribution.

I'd hazard to say that you're OK at a 68 room temp. That's probably pretty good for almost the middle of winter.

Sounds like you'd only require a very small heater in anycase. Or if your tank is portable, maybe place it next to an appliance that's always running - such as the fridge.

its alittle big for that But maybe I'll scooch my hermit crab tank closer so the heat lamp is near it... that thing warms up the whole corner of the room pretty good

Corydoras julii will be fine at 68 degrees. In fact they can spawn at this temperature. C. julii is very often confused with C. trilineatus. C.julii has smaller spots and is not as big in stature as C. trilineatus.
