sexing

This is my big orange fish. It is 4 years old. It has been alone in a 75 gallon tank since the day it killed everything in the water. I have tried both bigger and smaller red devils Midas and undesirable flowerhorn of both male and female with no success. It will relentlessly chase and kill...

Could someone tell me what sex my FH is and what species of FH it is?

I think 2 males hby

Hi everyone, im currently in the process off setting up my first flowerhorn tank and came across this little guy for sale. Fish is roughly 2". Just wondering if anyone can sex it & I.D what type it is. Any info and opinions are appreciated. Thanks.

I know this has been posted a million times here. Looking for opinions. Male or female? Just about the 3in mark.

I'm fairly confident that one is male and I wasn't sure on the other. I pulled them out today and got some photos of their vents/tubes/underside. What do you think the sex of these fish are? Thanks

Hello All! I'm new to the forum and this is my first question ever. This site has helped me tremendously in the past and I'm excited to join it. Is anyone able to tell me if my Synspilum is male or female? He/she is about 7 or 8 inches. I hope I'm posting this question in the right place...

Ok so I have a jaguar cichlid that I would guess is between 10-12" in length and pretty girthy. In a 75 with about a dozen cons. I'm thinking I want to give him (I think he's a he) a mate. He's been through a rough life...well, more so a rough childhood. Anyway, I'd like to know for sure if it's...

I been looking for a female vieja and found a guy selling some, his unsure of sexes and I'm waiting on more pics, can anyone help me from just looking at them in this pic

Question: Someone mentioned to me I may have gotten lucky and have a very genetically sound EBJD bc he/she is growing so quickly and its temperament is more aggressive than most EBJD, closer to a regular JD. They also suggested I should try and breed him. I have never on purpose bred anything. I...

I've had this dovii for a few months I'm hopingbto add a partner for it but I'm not sure if it is male or female I've been told at the pet store that it's 100% male but I want to be sure b4 i buy another one. It's around 5-6inches and has been super shy but I was told that will change around...

This little guy has been terrorizing my entire tank full of cichlids and has nearly killed A flowerhorn and a green terror.. I'm trying to figure out why it only chases and trys to kill only the females in the tank but yet only allows the female convict anywhere near it. I thought it was a male...

Bought this Rheoheros through my local fish store about a month ago, was labeled as a Theraps lentiginosus but has a pinkish hue to it which some coeruleus develop but not sure. Any suggestions or sexing advice here?

This is my dovii.. About 5", not shy at all and ears like a pig and is growing pretty fast.. I was told its a male from the guy I got it from.. Im just impatient and really want a male! Opinions please! Thanks!

Well i have three Salvini and so far two have been tail slapping and showing sign of pre spawning behavior. The fish are 2.8 - 3" and i was convinced i had three females. So are they really females or is one a male i only took a pic of the two who were showing signs of pre spawning behavior.

Hello everyone I hate to ask due to my inexperience but I recently moved my Mesoheros ornatums/gephyrums and I was able to snap a few photos. I'm far from an expert on this species and was sold these as a male and female. After looking this may not be the case but I'd love any input from you...

Does anyone know how to sex a moray eel or if anyone has bread them in captivity?

My first post here, thanks for any help. Love the site. Me and my wife have been trying to get our what we thought was a male/female couple of JD's to spawn with no such success in two years. Tried all the tricks and no action lol not even egg attempts like my O's. So I'm now...

I got a baby Jack Dempsey cichlid awhile ago. Can you help me figure out what gender it is? I'm not planning on breeding it I just like to name my fish. Lol
