sexing

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!

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...
