sexing

Hey guys! So I’m a bit concerned/confused about my gold nugget molly named July. I got her about 6 weeks ago, and then about a week later I got a male Lyretail molly (named Ember). July was most definitely a female up until today, as you can see from the first picture of her. Ember definitely...

Can someone please help me sex these two? Not the best pictures as they are quite skittish. I’m thinking white is male and black is female just based on how round they are and forehead look but I have no idea. They are still small about 5cm of body (no fins). White was being bullied in the...

We have just added 2 honey gouramis to our 65 litre tank. We are new to fish keeping. Can anyone tell me if they are male or female? I have attached pictures They have pretty much constantly been following each other around and tapping each other with their ventral fins since introducing over...

Hey everyone, Just wondering if I can get some help sexing my 2 new rams. I’ve been looking up online how to sex them but one of them I am stuggling with. I think the latter one is a female however the first one appears to have traits of both male and female rams so I’m struggling to identify...

At first I thought because the one had more color it meant male but I'm sure. Thank you!

Hello all, I've been keeping an aquarium for about a year now and so far, things have been going pretty well! But recently I splurged on a new tank setup and, after cycling was complete, decided to fill it with a bunch of neon tetras and a pair of blue rams. The local fish store (which has...

I'm pretty confident I got a pair (I watched them for an hour to make sure they were bonded and wouldn't kill eachotger before I got them) and I've had them for a few months and I just wanted to double check :) tank is cloudy because I redid the tank including adding some new sand

I have a gold and a blue variant. Here are the pictures. I apologize for not getting a picture of the full dorsal fin, but he only let loose when facing me. The blue ram is new and getting bullied so I can't get better pictures. Thanks for the help!

Hello again! Can someone identify if this is male or female lyretail creamsicle Molly? I have a make Dalmatian Molly in my tank also and know that the Dalmatian Molly is a male. He constantly is chasing my lyretail and rubbing his nose on the lyretail’s belly like an attempt to mate or...

So I bought this flowerhorn from ebay earlier this year. Personally I think it's a female but the eBay ad said it was male. Does Doug have poor genetics or is he a different type of FH as it also said he's supposed to be a super red dragon FH, but he has little to no red. Much appreciation in...

I was looking for a female BNP. I already have a boy so when I went to LFS I specifically asked for a girl. We found a BNP wit no whiskers on the head so I assumed it was a girl and the guy in the shop assured me it was indeed a female. I have her/him for roughly a month now living with my other...

Hi, I did post about this bristlenose a couple of weeks ago. I had a hunch it was male when bought as female. Since a couple of weeks ago, his/her bristles have grown even more. And grown on his/her head - which by my understanding would mean it was male but I’m no expert so wanted to check to...

Hi, Please could I have some help sexing my bristlenose? He/She is around 8cm. It was bought as a female blue eyed bristlenose but with the bristles I’m a bit concerned that she is a he. Sorry for the terrible photos. If you need more in different angles please just let me know. Thanks in...

Hi, I was just wondering whether my pleco is a male or female please? I always believed him to be a male but it never really mattered as I only had him but now I’m considering getting him/her a friend. Thanks

Picked up a pair of GBR's and was wondering if anyone else can confirm the sex of them. I did spend some time taking a look at both of them and think I have both a male and female. The supposed female holds the back of the tank and they both seem to get into a "fight" when they see each other...

Heya! so I've got three honey gourami, one male? in sunset colours who's starting to show some black on the cheeks, one wild coloured variant lady?? who I got from a really renowned fish store but who is now starting to show a black nose to anal fin and white dorsal, is she a he?? and another...

I know it's been asked plenty of times about mollies, but my lyretails seem to be a bit harder to tell, just because with the cases of heavy inbreeding I'm not sure if it's a deformity or just a very pronounced gonopodium. Also, I cleared the algea right after this picture. They just get too...

I'm new to tropical fishkeeping! Recently added some guppies to my tank which I were told were male but I am starting to think the black one is female? Mainly because lack of colour, shorter tail and rounder body compared to the others. Just wondered if anyone could clarify through the photos...

Hello! I’m sure this is a very common question, but I was hoping someone could help my ID the sexes of my guppies. I rescued a “Noah’s ark” assortment of tons of fish and that included two young guppies. I’ve kept them in a nursery box because they were so small and plan on releasing them into...

I have moved my One of my Jack Dempsey into a tank on his own as it is just not the same size as my others and after a recent ram casualty iv moves him into his own 3ft 35g tank I have two and wonder if I have a breeding pair so he could have a tank mate ? Can any body sex these I thought two...

Hi All, I’m new to this so go easy on me! Last week I bought 3 female swordtails to go with my current male swordtail. Unfortunately 2 died and this is the last one however I am super confused. It has a gonopodium, suggesting it is a male however it doesn’t have a long sword. It’s rather large...

Hello, I’m unsure if these red tuxedo x guppies are male, they’re a few months old but exhibit signs of both sex: As you can see they have stripes on their body and what looks like gonopodiums that they move around (left, right, tucked) as they swim. It’s also hard to see the gravid spot because...

Hello all! I’m relatively new to fish keeping but I love it so much! I got some new corys yesterday and I was wondering if anyone could help to identify their sexes if possible! Here are the two Juliis. I think the one in the back is female and the one in front male? (guessing! lol) Here’s...

So I got a paradise fish 2 weeks ago and I tough it was a male and now I am not sure because I think I saw him lay eggs. If the PF is a female, is she gonna be happy alone? One last question, are they picky at food because I got her/him fluval bug bite for small to medium sized tropical fish...

Hey guys, recently gotten back into the hobby after a few years of absence. School work etc... Anyways I have purchased a single German Blue Ram. and i want to get it a mate in attempts of breeding. Pretty sure this one is a female. Would appreciate if someone could confirm or tell me otherwise...

I’ve had this pair of apistogramma cacatuoides for a couple months And I’m starting to doubt my assessment of their gender. I got them from Petco and they sell them as assorted. I assumed that the one with all of the orange and black was male and the pale one with the black ventral fins was...

Hi all! I'm new to cichlids and am looking for any information on the Honduran Red Point/Convict cross. I bought six juvie HRPs after hearing they are a less aggressive convict type, later realizing that most if not all fish sold as HRPs are crossed with convicts somewhere down the line...

Hi, does this look like a male and female?

Hi, I am new to pea puffers and am having trouble sexing my puffer. From what I’ve heard females tend to have less spots but this one seems to have a rounder belly. Could someone please help sexing it? Attached is links to images and to the folder they’re in in my drive...

hey! I’m new to dwarf frogs and trying to figure out the genders I’ve got! Photos with a blue 1 on them I think are a boy. Purple 2 I’m hoping is a female. Let me know if I need better photos! Yes I know the frog is in a weird spot in one of the photos, it’s still getting used to the tank and is...

Hi, I'm very new to the tropical fish hobby and at the moment I have a Gourami, Balloon Molly, Swordtail and Molly, they've all been together for about 1 week. Yesterday we noticed lots of fry in the tank, but we completely missed the birthing process and realised we have no idea of the gender...

I recently got 2 sunset platys and I originally thought they were both boys. Especially since the bigger one chased the littler one around a lot (it doesnt do that anymore though, for some reason. Maybe they worked it out?). But after some research apparently, the girls have rounder, fan-shaped...

About two weeks ago i got 2 Angelfish juviniles off my friend who is a breeder here in NZ (about 3 months old from fry to know). I also have another 4-5month old Marbled Angel in my tank so they all not to big. I have a few questions, one is considerably smaller than the other two and just...

My son got a fish tank for Christmas. It has been populated with plants, snails, 7 cories and 3 swordtails for a couple of months, now and the fish all seem happy. Here's the part about the sex of the swordtails... We bought what I thought were two females and one male. I honestly thought...

Hey everyone, I'm new not only to here, but also to keeping tiger barbs! I know about the red nose is male and very round is female, but my tiger barbs are showing some signs of both. One of them is obviously female because she's very round, i think she may be carrying eggs, but the other two...

Hi everyone. Just some questions concerning my 60 Gallon Tank. Hoping someone can help. I have 3 Bolivian Ram's and one of them looks to be stressed as it's colors aren't normal. It's basically turned dark grey and hides from time to time. But every now and then comes out to swim around. Hasn't...

Hello everyone. I am looking for a bit of help. I've got two angelfish that I am trying to determine sexes for, I have a feeling both are female, but I've never sexed angelfish before.  Also I have been observing breeding activity between my swordtails, so I am wondering if they are pregnant. I...
