I Wish

[james331]

I wish someone would do a book or post online every species of fish and tell use which one is male and which one is female, or i wish someone can just tell me how to tell a fish if its male or female,

Try put finger into aquarium, if fish close up anal fins, assume male until proven otherwise.

Most of the subforums have sticky topics on the subject. Take a look. And Kujiraya, male fish don't have the equipment to really worry about a finger in the bum. Grow up.

Not necessary in a book but there are a lot books dealing with this...and to be honest, a lot of times, a picture of the whole fish won't help. And in case of fish like malawi haps, pictures of young fish won't help either.

[Kujiraya]

If fish lays eggs, consider as female.

Some species are sexually dimorphic, IE; Frontosas and the "nuchal hump" which is a big knob on the male's head. Some species differ in color male-female. Like Guppies, plus males (mollies, platies also) have a phallic-shaped anal fin called a gonopodium.. More than a few are NOT sexually dimorphic, females are just a little heavier in the body than males, like piranhas. Some, are not dimorphic until they're sexually mature: Male goldfish develop white tubercules on their gillplates. It all depends on the species of fish you're intending on getting whether or not it would be easy to sex the fish.

I had a 11 inch female Burundi frontosa paired with my 12 inch male Burundi frontosa and my female had a big hump then my male so it means nothing venting is the most practical way to determine sex but isnt always a sure thing either like stated above to be 100% positive wait to see if they lay eggs or not
