Dicrossus filamentosus temperature question

[anewbie]

Is 78 too cool for very young Dicrossus filamentosus; they are around 3/4 of an inch. I know some fishes breed during warmer times but i can't find a stable # for Dicrossus filamentosus. Some seem to suggest they are blue rams oriented wanting 82 others are even higher with discus around 84 and a few seem to suggest 78 or 79 is fine.

Actually most SA cichlids breed all year around - but mainly during the wet season when there are more areas that are flooded and more breeding territories are available. As hobbyists we mostly get environmental values during the dry season because that is when most locations are more accessible. 78°F/25.5°C should be fine.

This can’t be coincidence. I wanted to post a question.
Yesterday in the early afternoon, my pair of Dicrossus filamentosus spawned on a sword plant. The female is guarding the eggs very well. After 24 hours, the eggs still haven’t developed any fungus.


However, the pH is 6.7, the hardness is 5 °dH, and the temperature is 26 °C. Everywhere I read that the pH should be much lower. They are wild-caught “Orinoco” fish (not that this tells you very much).
Does this happen often?

First i find ph to be a red hearing - total softness seems more important. My n. transvestitus spawned in 'higher' ph then most articles suggest but the ec was around 40. The 5 dh is probably more important.

Also be aware that until you confirmed the eggs are fertilized it does not mean the spawn was successful. non-fertilized eggs will not fungus immediately but will turn white after a day or 3. If they do turn white chances are the water is too hard.

I've had this problem with several fishes when i used to use tap water.

To develop viable offspring the EC should be below 50 micro-siemens /cm, pH of about or under 6 is optional, but not a must. Temperaturewise 27°C were optimal for growout in my experience.

I will reply to both MacZ and Anewbie.
Thank you both for your response.
I never intend to breed with my Discrossus. I bought 6 of them a year ago just because they were there, cheap, cute and so on. I was under the impression that they wouldn’t even attempt to breed if i didn’t meet their parameters. I’m just very surprised that they spawned at all. But i can extract from both of your responses that spawning is absolute possible but the chance of fertilising or hatching is (almost) zero

You didn't make the impression thst you intend to breed, I just wanted to give information that might have value to you. If you take from this, that you don't have to worry about the eggs hatching: Goal reached.

Well if we raised dinosaur there would be the advantage that when they tired of us they could dispose of us fast enough. Something our dwarf cichlids haven't quite figured out [yet].
