Okay this thread is going to be a bit of a rant i warn you but i am raising some important points i believe...

..."cough"....

Ok in this thread i want to raise some issues facing livebearers and how i believe most of them stem down to the fact that they are considered "beginner fish"...
When somone says "beginner fish", what things first come to mind? Tough fish that can live in bad water quality and no specialised diet, sturdy fish that are easy to stock and don't grow huge, fish that don't need large tanks and are pretty care free as far as tank maintanence and caring is concerned, etc etc...
Out of all the fish out there, livebearers don't make bad beginner fish but that doesn't mean they don't need alot of care or maintanence- all fish should be given good water quality conditions, diet and the right size tank when it comes down to it.
But many people veiw livebearers that don't need all this all these certain elements of fish keeping attended too so greatly and can be made an exception of with them.
FACTS;
a. the MINIMUM tank size for any livebearer is 10 to 15gallons.
b. Mollys and swordtails can easily produce up to over 100fry and their fry take up to a year to mature. Guppy and platy fry take between 4 and 7months to mature.
c. Guppys and platys can produce fry up to once a month and can easily produce over 30fry a batch- somtimes over 50 is not that uncommon.
d. All common female livebearers(swordtails, platys, guppys, mollys etc) can store sperm in them for up to 7 pregnancys meaning that they only need to be in contact with one male in their lives to produce fry at any point, so all-female groups do not prevent fry.
e. All-male groups are posible but tend to have more issues than mixed gender groups and need to be stocked much more slowly in much bigger tanks than mixed gender groups on average. Most all-male groups need a minimum of 5males to work well at all.
f. The minimum mixed gender ratio is 2-3females per male, but and extra female needs to be added to this ratio for every male after one male and even so this is may not totally neutalize conflict and harrassment between males and females.
It is near imposible though to have more than one male swordtail in a mixed gender tank without them trying to kill each other- we are talking at least 15females between 2males.
g. Salt is not essential for mollys to be healthy and they can live happily without it, although salt cannot be used with "scaless" fish and it is not good for long term use with other livebearers, it does make an effective med against deseases like finrot though although what it can cure is pretty limited.
h. There are 3types of molly- standard/common ones, sailfins and balloon mollys. standard mollys grow to about 3-4inchs, sailfins can grow to 5inchs+ and balloon mollys get to about 2-3inchs.
Swordtails and sailfin mollys need a minimum tank of 15gallons and this applys to other types of mollys although technically 2 standard or balloon mollys of same gender can be put in a 10gallon tank.
i. Inbreeding should be avoided in all types of livebearers as many are already very inbred and it has many bad effects which are already very apparent in many livebearers, particually guppys and platys, and it is very irresponsable to worsen this effect on the species knowingly.
j. If you are to have all-female or mixed gender group of livebearers, be prepared that they will breed and have fry no matter what. You should not just cull fry automatically everytime you get them as this is very irresponsable behaviour and you should not be having these groups if you know you cannot look after any of the fry- i am sure many betta people would be in an uproar if somone posted on the betta section that they were going to breed bettas and then cull all the fry or all apart from 5 or so because they knew they didn't have the space for them, i don't think this should be any different for livebearers.

..........
It is amazing how many people do not take note of these simple facts! I think livebearers are often abused fish and it gets me angry.

There are many people dedicated to breeding top quality livebearers- there are competicions with big money as prizes and clubs that are dedicated to them entirely and i think they are just as much of an advanced fish keepers fish as a beginners fish.
It seems to very accepted and understood that if somone gets bored of their guppys they move on to another type of fish, but i know this would not be the case if it were a rare plec or betta or cichlid etc- why should it be so different for livebearers and why is there so much less responsability over them...??

I hope anyone who is about to get a livebearer takes all these factors into consideration, thankyou for your time and any comments are appreiciated :) .
 
The thing is that livebearers are easy to keep compairatively and they do something very interesting, they breed. Also mollys DO need salt, they are NOT fresh water fish without salt they will NOT live out there whole lives.
 
i totally agree with you :D justy because livebearers CAN live in bad conditions dosent mean they should.......they deserve the same as any other fish,i think another problem is that theyre so cheap people dont really care if they die!they can pop to the shop and get another one in almost every pet and fish shop for under a £1 :thumbs:
 
So as I keep standard mollies, sunset platys and guppies in a 27g is it good to add salt or would that be bad for gupps and platys?

Actually i did a thread on salt on mollys a little while back- you should read it too; sailfin mollys live in both freshwater AND brackish enviroments in the wild and can be kept in either happily. Sailfin mollys though are a bit more on the brackish side than standard mollys, which prefer on the whole to live totally in freshwater.
 
all livebearers can live with salt, and as Opcn said, it will make them live longer then with out it.

and a little FYI...sailfins can slowly(over a period of time) become true saltwater if you add salt slowly and carefully

Hmm, im not sure on salt with other livebearers that are not mollys- guppys and platys for example have never lived in brackish enviroments in the wild naturally, so i doubt it would do much to extend their lifespans- the only reason why it can benifet mollys is because they have evolved to tolerate it in the wild but this is not the case for other livebearers.
 
Thanks guys, my molls are standard so I think I'll keep them in freshwater
 
Mollys will live longer in light brackish than fresh.

Standard mollies get the shimmys too, that only happens in fresh water because it is a salt defficiency, Fresh water is also harder on the kidneys. In the wild standard mollys are found in freshwater lagoons and slatmarshes, both places that undergo lots of evaporation and as a result get high levels of salt compaired to rivers in south america were there is very low salt content, but the mollies arent found in the rivers. Also Sailfins aren't found in freshwater, they are found in brackish to full salt. Most of the livebearers can handle light brackish and it will make them prettier but of the common livebearers mollys are the saltiest, they really do need salt otherwise they could develop nerve issues including the shimmys. Would you link me to this thread so I can have a look?

Also, Cheap fish that can handle newbie mistakes are better than expensive fish that can't. We recoment WCMM's and ZD's instead of other attractive fish like percula clownfish or angelfish. Its much better to harm a few easily replaced fish than it is to kill a few that cannot be replaced easily, besides what on earth are breeders supposed to do with all the surplus fry?
 
Sailfin mollys though are a bit more on the brackish side than standard mollys, which prefer on the whole to live totally in freshwater.

Actually, I must disagree... I've kept a few mollies for a year or so (in perfect tank conditions, I might add) and they absolutely do not do well without at least a tiny amount of salt in their water. Mine have come down with a body fungus each time I removed the salt from the tank. All other fish were unaffected... no signs of disease on them whatsoever. This leads me to believe that they do require salt in order to stay healthy.
 
Hm it differs much for me- my 2 female mollys who i have had for a year and a half and never ever been ill or had any desease in the time i have kept them and have always been in the best of health without ever having salt in their tank for anything.

I don't know why, but as I said, mine do not stay healthy without salt. :dunno: Are there any valid tests that have been done on the subject?
 
The mollys i have are just plain old standard ones, the females have been rasied from fry and are now a year and a half and the male molly i have had for about a year and is 5yrs old.
I do not know wether there has actually been an official study into how molly health and life expectancy is effected by the presence and lack of salt- the average life expectancy for a molly is 4-5yrs though, so i will be able to give an answer to the question of salt and mollys in 3 and a half years time with my female mollys but i know it would be more useful to actually find somone who has raised a mollys in brackish and freshwater from fry to natural death.
I suppose alot of it must come down to the individual molly as there certainly seems to be no full answer to the debate though yet. If my mollys ever got ill with a salt treatable desease i would personally use salt over meds to treat them but so far they have never been ill -_- .
