There are no visible differences between male and female Green Spotted Puffers. It is thought that the male is slightly larger than the male, but this is unconfirmed.
Breeding Green Spotted Puffers in captivity has never been recorded, but there are several theories about it (such as providing a large tank- 120+ gallons, a sand bed, a slate stone, and bog wood).
The male may be slimmer and the female more rounded but this is also unconfirmed. There have been a few records of them breeding in aquariums but none done commercially.
It'll be smaller than a male and more dull in colour.
No, puffer fish lay eggs. The female releases eggs into the water, and the male fertilizes them externally. The eggs hatch into larvae, which develop into juvenile puffer fish.
To the best of my knowedge the majority of Puffer fish species show no sexual dimorphism. You may get more detailed and better information however in the sea water aquarium category.
Green Spotted Puffers (and most other puffers) are nearly impossible to breed in captivity, and exact procedure has never been recorded. It's thought that the female will lay her eggs on a slate stone and the male will fertilize and fan them with his tail, not much else is known. But it's entirely possible the male will eat the eggs, and the young. GreenSpottedPuffer.Net
a female
it depends on the puffer fish they mostly lay lke 3 or 4 eggs I think it 3 or 4 eggs it some times depends on the pufferfish Im prof.caler send me a e-mail at calers@qkstream.com
There is no gestation period for Betta splendens. They are egg layers. The male looks after the fertilised eggs in a nest of bubbles that he makes. Once they become free swimming fry they have to be separated from him before he eats them.24 to 72 hours :)
Porcupine fish reproduce by external fertilization, where the female releases her eggs into the water and the male releases his sperm to fertilize the eggs. The fertilized eggs then develop into larvae, which eventually grow into juvenile porcupine fish.
Feeder fish, How do you tell male from female of the?
Do you mean female and male? If so, then the female betta fish is smaller and less elaborate than the male.
male
There are two possible phenotypes and genotypes for the male. We know that neither the male or the female can be S/S (S = spotted, N = non spotted) because this would result in all of the pups being spotted due to spotted being the dominant gene. Therefore the male must be either S/N or N/N, However the S/N genotype gives the 1:1 ratio of spotted to non-spotted (assuming the female is as well) which is what the pup ratio is, so we can assume that is the male's genotype.
