They were breathing fine when I let them out of their bags. It wasn't until that water change that the rapid breathing began. A few from each species were rapidly breathing i.e. polit, demasoni, and perlmutt. They are fine today, everyone is swimming around and even eating.
4X daily for fry. 2X daily is fine for small juveniles. Are they 1.25" including tail?
When you change water, know your temperature, pH, ammonia, nitrite and nitrate before the change. And then make sure when you change the water make sure all the parameters are the same with the water you will use except 10ppm less in nitrates. Don't forget the dechlorinator.
Some are actually 1.5-1.75" but a have a couple tiny ones that are 1.25" total length. Have you had to do two consecutive water changes because nitrates were too high? Water changes are time cosuming even with a python.
I bought juveniles because I couldn't afford adults at $11-$19ea...the <vendor name removed> seemed to have picked me out some males and females from what I can tell and acccording to their policy on unsexed juveniles they try to choose a ratio depending on how many you purchase. For instance, buy 5 you get two males andn three females.
Since the fish were in the tank after the first water change and before the second...they only had to experience the change you did to get from 20ppm to 10ppm. That should not cause a problem. Do you think the parameters were identical except for nitrates between the tank and the new water when the fish were in the tank? I would not do two in a row, I would do one change with a larger volume.
2m:3f is not an ideal ratio...but hard to tell how they can sex at 1.25", so nothing to worry about for a month or two. Although some can spawn at 1.5" so keep watch for fish lurking under the surface or behind intakes and heaters.
It takes me around 40 minutes to do the 72" tank and 20 minutes to do each 75G tank with the Python.
I agree, I don't know how they can tell them a part so young but a couple do have egg spots already which means male I believe. Some are much larger than 1.25", I think I have two that small, some seem to have more vivid colors already while the polit cichlids are still in their juvenile colors. Cross my fingers the ratios are better than 2m:3f. For instance, one demasoni has egg spots and vivid colors while the rest are dull or washed out in color and all are at least 2" (eyeing it).
Egg spots mean little. Females absolutely have egg spots.
A washed out fish can be a harassed or subdominant fish...male or female. Demasoni are monomorphic (males and females same color) so intensity is likely a factor of dominance rather than gender...females can be dominant.
Polit may have a hard time coloring in a tank with demasoni...but it would be a beautiful sight if you are able to accomplish it.
This is so much more complicated than keeping monitor lizards, lol. I have so much to learn so I guess this being my first time around I should be easy on myself. The biggest polit seems to chase away the most dominant demasoni, most colorful specimen. You know I did my research, I have books on the evolution of cichlidae but I still feel lost, lol. Books have helped me very little as most books I have are old or only cover very basic things. I tried to match cichlids by aggression using the resources on this forum (fish profiles). I tried to keep them small as adults 4" or less since I only have a 55 gallon. I bought 15, five of each of the three species as I tried to keep the bioload down on newly cycled tank. So I can only hope to get a sex ratio that works out or maybe I'll have an all male tank or female (hope not).
