Males or females?

Are these two males or females? At first we thought they were females but they look like males. I have to know quickly because we only have 1 confirmed female and 1 confirmed male in the tank, if these are both males we need to balance it out with females quickly so the female doesnít get hurt. Let me know? Thanks.

Note: My boyfriend and I are the owners of two tanks right now. We are still relatively new and learning more and more. We have had fish for over a month now and trying to figure out everything.

Need some better pictures with the anal (bottom) fin flared out.

With common livebearers like mollies, guppies, platies and swordtails, the anal fin on the males is long and straight. The male's anal fin is called a gonopodium and is used to impregnate the females with a sperm packet.

The female's anal fin is fan or triangular shaped.

----------------------

It is preferable to keep common livebearers in single sex tanks (all males or all females). This stops the males harassing the females.

Female common livebearers can carry sperm packets from previous matings for 6 months or more and use these sperm packets to fertilise batches of eggs without the males being present. If the female/s have been in a tank with males for a day or two, they will be carrying sperm packets.

----------------------

The silver molly with a few black dots looks a bit skinny and might have intestinal worms. Common livebearers from fish farms usually carry intestinal worms.

You can try feeding them a bit more often (if the filter is established), and if there is no improvement in a month, then deworm the fish.

----------------------

DEWORMING FISH
Intestinal Worms like tapeworm and threadworms cause the fish to lose weight, continue eating and swimming normally, and do a stringy white poop. Fish can do this for months and not be too badly affected. In some cases, fish with a bad worm infestation will actually gain weight and get fat and look like a pregnant guppy. This is due to the huge number of worms inside the fish.

Livebearers like guppies, mollies, swordtails & platies are regularly infected with gill flukes and intestinal worms. If the fish are still eating well, then worms is the most likely cause.

You can use Praziquantel to treat tapeworm and gill flukes. And use Levamisole to treat thread/ round worms. If you can't find these medications, look for Flubendazole, which treats both lots of worms.

In the UK look for:
eSHa gdex contains praziquantel that treats tapeworm and gill flukes.
eSHa-ndx contains levamisole and treats thread/ round worms.
NT Labs Anti-fluke and Wormer contains flubendazole.
Kusuri wormer plus (contains flubendazole) - sold mainly for discus, comes as a powder which is quite hard to dose in smaller tanks
Sera nematol (contains emamectin)

Remove carbon from filters before treatment and increase aeration/ surface turbulence to maximise oxygen levels in the water.

You treat the fish once a week for 4 weeks. The first treatment will kill any worms in the fish. The second, third and forth treatments kill any baby worms that hatch from eggs inside the fish's digestive tract.

Treat every fish tank in the house at the same time to prevent cross contamination.

You do a 75% water change and complete gravel clean 24-48 hours after treatment. Clean the filter 24 hours after treatment too.

Do not use the 2 medications together. If you want to treat both medications in a short space of time, use Praziquantel on day one. Do a 75% water change and gravel clean the substrate on day 2 & 3. Treat the tank with Levamisole on day 4 and do a 75% water change and gravel clean on day 5, 6 & 7 and then start with Praziquantel again on day 8.

The water changes will remove most of the medication so you don't overdose the fish the next time you treat them. The gravel cleaning will suck out any worms and eggs that have been expelled by the fish. Repeating the treatment for 3-4 doses at weekly intervals will kill any worms that hatch from eggs. At the end of the treatment you will have healthier fish.

The chocolate molly looks like a female.

Any chance of different pictures or video of the silver one so we can see its anal fin?
