What the heck are these? :)

mollies can grow much larger than guppies,sailfins can grow up to 12 cm or 4 inches,i hope i am right,not so good at converting
 
Mollies - no question. I particularly like the top one, but I have a penchant for fish in their natural colouring.
 
To be or not to be ??

Dear ArkyLady,
From what I've generally seen they certainly look like a strain of mollies to me. The first pic looks like a female Redtail Mollie however you never know there are so many strains of Mollies. I'd SAY the second one is some kind of Albino Lyretail Mollie or maybe even a White Labyrinth perhaps ?? Who the heck knows for sure like I said there are tonnes of different strains of Mollies nowadays. A word of advice to you keeping them happy, they benefit from being fed Red Mosquito Larvae and also Freeze Dried Tubifex but be careful not to overdo it with Tubifex, it makes a mess BIG TIME and it's kinda nasty stuff to clean up :p You can also try adding salt to their water in small quantities but if I were you I'd talk to a breeder or reputable Pet Store about what kind of salt and how much you should use depending on your tank size. Try keeping the temp around 78-80 degrees, perhaps even a degree or two higher when they are breeding as this usually makes the fry develop faster !!!! However if you notice mom is fanning her eggs or the fry constantly you may wanna turn it down a notch. Just glad I can be of any help to ya and good luck with the "kids" and happy fishkeeping :D


Best of Luck and I wish you Well :)

i completely disagree,mollies are livebearers,they don't fan their eggs,temp diff doesn't affect the growth,you obviously don't know about fishes FISHGUY_CA
 
Agreed with Serrateeth on the part that mollies are livebearers. Thus, they don't lay eggs. However, a temp diff may affect growth. Generally, with a higher temperatur, a fish's metabolism will increase. So I hypothsis that a slight increase in temperature may increase overall growth. However, it will also slightly decrease a fish's lifespan.
IMHO, don't bother with a temperature increase, keep your tank at a normal tropical temperature, and leave it at that.

I've been keeping them at 78 degrees. I suspect that the albino one has some ich (somewhat hard to confirm due to her coloring though), so I bumped the temp up to 80 and started medicating them.

FYI the white mollie with black spots had babies the day after I posted and 10 or so are alive and doing well. The albino one had her babies while I was sleeping, but I can't find any of them this morning. Not sure if they're just hiding too well for me to see or if they were all eaten :(
 
I'm going to move this thread over to the General FW forum since this is not directly a beginner's question ! :)
 
ever find out what you had? im thinking the 2nd picture is a silver lyretail maybe and a dalmation molly. as for the first picture, im not sure but maybe a mosquitofish? here's a link to check out:
