how can you tell the difference between a male and a female fish.?

Question

i have some guppies, angel fish,zebra fish and 2 neons. how can i tell if they are male or female?

Answer 1

In some cases this is an easy thing to determine and in other cases it is quite difficult, if not impossible. The reason is the wide variability between species of fish.

The differences between the sexes of dimorphic species may be subtle or quite remarkable. Livebearers belonging to the family Poeciliidae (mollies, guppies, swordtails, platies, and wags) are easy to distinguish. The male fish possess a gonopodium, which is a modified anal fin used for copulation. The female fish's anal fin is shaped like a triangle. Sexually mature males of many New World cichlids have a large hump on the head. In some cichlid species, the male's dorsal and anal fins are much longer and larger than the female's. During Spring, the male goldfish develops numerous small bumps on the head, opercula (gill plates), and pectoral fins. These bumps are called nuptial tubercles and usually disappear at the end of the breeding season. Sometimes,they are mistaken for external parasites.

The sex of some species, e.g koi, are difficult to determine unless the fish are ready to spawn. In a koi pond, the females will generally be larger and more full-bodied than the males. In addition, a female ripe with eggs will have a swollen abdomen which will set her apart from the more streamlined males.

Answer 2

With the guppies the males are more elaborate with brighter colours and longer fins. The difference in sex between the neons will be in the length of their neon stripe, the females is shorter and the males run all along the body, with the others I'm not sure, but they will have either slightly different body shapes or fin length (or both)!

Answer 3

This website has all the info you need for lots of fish:

Basically:
Guppies: male has long pointed anal fin, large showy tail

Angels: can only tell at breeding time

Zebras: Adult males have some yellow, smaller than females

Neons: male is smaller

btw: if it looks like a neon has a red stripe it's entire length, it's a CARDINAL tetra

Answer 4

For most fishes, males are always fancier than the female ones, and are sometimes larder too!

Answer 5

Anus of male w'd be depressed & pectoral fin w'd be some what harsh but in case of female Anus w'd be some what swollen & pink as well as pectoral fin w"d be smooth & sleepy.
