Seems to be fine at room temperature. I don’t use a heater and it breeds okay. Any other opinions or experiences?
Well, living in Canada, a heater is a must. I’ve had mine for about a month and they seem to be happy at 23°C. Not too sure about breeding, the 2 females seem to have swollen abdomens, so maybe it’s just a matter of time, but we’ll have to seen. I’ll take some pictures real soon.

My fry seem to be happy in 24°-26°C.In lower temperature fry is not feeling well and not eat very well.
Adults can be in temperature about 22°C,for spawning this temperature also enough.Thanks Karel, good to know! I’ve heard of of this situation for other types of fish where the fry need higher temperatures. I might need to get another tank with heater just for these little guys…
Mummymunky – can you define “room temperature” for us?
I think it’d be best if those of us who have successfully bred the fish all report in on the temperature they bred at, so we can get an idea of what the “ideal” range is.
So far I see the following reports:
Karel reports that they have bred at 22.Anyone else can report in at what temperature spawning has occurred at?

Well, I suppose when you ask a vague question, you get a vague answer.
I was actually hoping you could remember exactly what the temperature was when your fish bred. “Room temperature” can be different for different people. (I’m imagining that in Perth, it’s slightly lower than it was here in London yesterday, for example.)
I liked your answer though.

They breed all the time. Every day there are new fry. The temperature varies, I wouldn’t worry about it. When they started producing fry it was December and the central heating was on. Now the heating is off and there are still new fry. Set it for the low to mid 20s C and you’ll be fine.
does anyone had any success breeding at temperature above 30c? whats the ideal temperature anyway? my tank is between 30 c to 35 c. they’re all ok. but not yet breeding. its a very well grown planted tank with only cpd in it.
Mine are kept constantly at 24C and are constantly breeding, I had them at around 20C for a while and they didn’t like it.
Fry are raised in 26C and seem to grow quicker for some reason.
1 of mine mysteriously died last week. but the rest is ok. no death after that. there’s eggs inside the tummy. i hope its an indication they can breed above 30 c. will have to wait some more i guess.
30C is a little high for most fish, isn’t it? Especially fish that like cooler temperatures, like CDPs. Most fish, in my experience, would certainly be showing signs of temperature stress (unless they’re being treated for something, and it’s only for a short time).
The vast majority of tropical fish (with some exceptions, like discus, who like it a little warmer) prefer temps between 24C-27C (76F-80F). That three-degree difference is a big deal if you’re a little fish!
30C is a little high for most fish, isn’t it?
Not necessarily in my experience
My apartment is top floor and during the summer time we are boiling :lol:Temp in my tanks reach 30-31’C. Since O2 levels get low during high temps I do add another power head or an extra air pump and I create a strong surface agitation and I keep the filters clean (meaning they are never clogged).
I kept Celestial Danios in a 180 litres without any problems. Not sure if they breed with such high temps but I did see males displaying fins to one another.
Also, since higher temps sink O2 levels it is of utmost importance to improve the tank’s cation exchange capacity by adding some Zeolite stone or simply dosing cation exchange fluid products like EasyNeo (aka Easy Life FFM) or even the newly improved Sera BioNitrivec.
Why? Well less O2 for the nitrifying bacteria can cause slight NH4 or even NO2 spikes and for that reason Zeolite can do miracles in binding NH4.Regards, Dusko
Although many fish can survive for some time at 30C+ it will often cause them harm and stress and eventually death. If it can be avoided it should but UNLESS the fish in question hails from an environment where they live in such temperatures…i.e discus. I would say keeping cpds and most other danios at such high temps is a recipe for disaster. It speaks volumes for you as a good fishkeeper Dusko that you can keep yours alive.
