Re: [Killietalk] Cold water killies



Hi All, I just wanted to make a comment about some of my fish that get absolutely lethargic in warmer- conventional aquarium temperatures. My herzogi, oceallatum, bochtleri especially do not become more active, but opposite. If you argue that they just like more DO, then it means they like cooler water since dissolved oxygen is a function of temperature. The other thing that happens is a decrease in egg production when the temperature passes 20-21 C. I have never been able to keep them happy and colorful unless it was cool. Cold water killies vs cool water killies?

Mostly south american annuals: Simp, Campellolebias, Cynopoecilus, Austrolebias, Leptolebias.

Tank space is usually a 2.5G for 1-2 pairs with weekly 50% water change and peat replacement. I keep my water on the soft acidic side, and add a small amount of electrolytes.

Food is live blackworms most of the time, and baby/adult brine maybe twice a month. For fry, food is always baby brine.

Fish won't seem to do their thing until temperatures get to 76F. Even Campellolebias brucei did not lay an egg at 72F (I know, I know . . .but I invested lots of time looking for those eggs), but I was able to find about 30-40 in a pair's weekly peat at 76-78F.

I have not had non-annual cool water fish, but my guess is they'll do just great at 78F :)

take care,

It sounds like we need a little more information, ie, which fish have you tried? tank space? foods, just how cold are you working with, etc., etc.
