Matching Tank Temp During Water Changes

[JK47]

I do not have any links, but I do know livebearers kept in tanks with the opposite sex tend to live shorter lives than those that aren't constantly breeding. The same thing goes with bettas. I've researched this over a year ago and I don't feel like combing through "guppy breeding" pages on the web for stuff with useful information.

I don't think breeding occasionally shortens a fish's lifespan, but when kept in breeding conditions 24/7 it will. If SA cichlids breed without any sort of changes (large water changes that are different temperatures or certain diets) then that is a different story.

If they breed after large water changes with cold water and are fed a diet of only protein then they are not kept in optimal conditions health wise and will lead to quicker aging.



That is one point I was making, also if always spawning, fish use all their energy in breeding or some fish care more about their fry than themselves. The parents need breaks.

My apologies then, I misunderstood you. Yes I agree being kept in a constant state of breeding conditions would turn my fish from something I love into basically lab rats... I agree with you in that regard. My different species of Geophagus are far from livebearers. My geos spawn with or without temp swings during a WC. I have a certain species of Satanoperca that I am working with, little is known about spawning behavior and I have to control the temp and enviroment so I can replicate it in the future. I usually only make an attempt to induce about once a quarter. I refuse to use no heaters for the night etc... so WC's are the only time I can accuratly manage the temp.

Trouble is, everyone keeps trying to tell me how the temp needs this or does that etc... I get that. Again I never asked that though, I asked for experiences of how others were controlling temps. Sorry if I came off rude but it was getting off topic.
