tl;dr People says to dechlorinate tap water, or fish will always die. I've never done it during water change, yet fish are still healthy for many years. Is it possible that low concentration of chlorine is harmless to fish?
Any fish expert or something? I had these fish (african cichlids, plecos) for like many years, and I've always done water change (30-40% every week or 2) with the tap water (no dechlorinator or anything else). They've been and are still doing well to this day, breeding once in a while.
But now, I keep hearing you need to always "dechlorinate" tap water, or your fish will definitely die. So I'm really confused right now.. If there's low concentration of chlorine, would that make it harmless for fish or something? If I'm not wrong, there should be 0,080 mg/L chlorine in my tap water.
Been searching on google like crazy, but everyone keeps saying any trace of chlorine will kill your fish.. yet it's been 8-10 years, and fish are still there.
Anyone care to enlighten me?

I've been doing some research, but I'm sure some of you might be able to provide information I'll be unable to find easily, so here goes...
So, it appears that some species - even some primates - are capable of self-aborting a pregnancy if conditions aren't right, whether it be due to the appearance of a new male (Bruce effect), resources are not optimal (fetal resorption as seen in bears) or there is something wrong with the offspring (fetal resorption in some species of dogs).
This brings some questions to mind, namely...
1) How aware of this are the animals themselves? Is it merely a bio-chemical reaction taking place spontaneously (ie, the introduction - in the case of male pheromones - or imbalance - in the case of lacking resources/abnormal offspring - of a biochemical signaler resulting in further biochemical reactions that result in self-abortion), or do the animals themselves have some capacity to recognize circumstances at hand and activate a response?
2) In either case noted in 1, but particularly the former biochemical approach, would it be possible to engineer a human application, thus ridding humanity of the need for external surgical abortive techniques? Is this effectively what the morning-after pill does?
I'd rather not see this get into a debate on the morality of such a thing, and am merely focused on the possibility of its application.

As a long time member of /an/ I would like to say that I love you guys. And, as I am trying to get into the sport of free diving, I thought you m/an/iacs might be keen for a thread.
Clearly freediving is /an/ related and I don't really feel like trying to get /sp/ involved (although they are free to join this thread). This is a thread for training tips, apnea limits, competition achievements and freediving stories.
Also, posting this drunk, wearing my diving mask while running 02 tables.

I have a 2 year old female cat and a 2 year old male cat, both fixed, that I got from separate shelters. If I were to get a third cat (a kitten), would it be better to get a female or male? Is it likely that they'll fight when the kitten gets older?
The kitten in question is 4 weeks, which I know is generally too young to be adopted out. But the owner is set on getting rid of her kittens immediately. There is a particular kitten in the litter I'm really interested in (pic related).
My current cats are very friendly and never once have fought with eachother... only very brief hissing at eachother on the first day they met, but after a day they completely bonded. What's the easiest way for me to introduce the kitten to my cats?
